The trial wrapped up for the day, with the testimony of Jose Ibarra's brother postponed at least until the morning.

Diego Ibarra was called as a defense witness in the Laken Riley murder case, but his lawyer couldn't get to court in time Tuesday afternoon, so the judge ended trial for the day. The jurist said Diego could come back to court in the morning. It was not immediately clear if he would end up testifying.

The defense issued a subpoena for testimony from both Diego and a third brother Argenis Ibarra, who may testify Wednesday.

The pair of siblings -- Venezuelan illegal immigrants -- are both serving time for forging green cards and had to be transferred to the local jail to testify on their brother's behalf.

It was not immediately clear how many more witnesses the defense plans to call, but closing arguments could begin as early as Wednesday.

Defense witness Stephanie Slaten testified that Jose Ibarra's brother threatened to kill her the day of Laken Riley's murder if she spoke to cops.

Slaten lived in the building next to Jose and his brother Diego Ibarra and had slept with Diego, she testified.

She said that Feb. 22, when Riley was allegedly killed by Jose, Diego came and sat next to her on the stoop outside amid a heavier than normal police presence and asked what happened.

Slaten said she told Diego that a girl had died and urged him to tell cops if he knew anything about it. Officers then approached her asking what she and Diego were speaking about and she repeated what she said, the witness testified.

Diego hissed to Slaten afterward: "If you tell them, I will tell them that you did it, and then I will kill you, too," the Slaten recounted. 

It wasn't clear what Diego might have told Slaten, prompting him to threaten her if she talked.

On cross-examination, prosecutors took aim at Slaten's credibility, getting her to admit she had been drinking that day, that she is currently out on probation and that she had slept with Diego.

She also revealed that she had bought Diego a cell phone so he could find a job and discovered a video of some girl dancing with Diego at a club. Slaten admitted she accused Diego at one point of "f--king" another woman.

Diego -- who is currently serving time for forging a green card -- was the next witness to be called to the stand but he didn't end up testifying Tuesday, as his lawyer couldn't make it to court in time.

As he sat on the witness stand while both sides discussed the matter, Diego wiped tears from his eyes at seeing his brother in the courtroom.

Laken Riley’s accused killer Jose Ibarra chillingly spoke for the first time in court, telling the judge in a low voice that he would not testify in his own defense.

Judge Patrick Haggard went over Ibarra's rights, explaining he could testify but that it would not count against him if he didn't.

"Mr. Ibarra, do you want to testify?" Haggard then asked.

Ibarra shook his head and said, "No'' in a low voice before a Spanish translator repeated, "No, sir."

This is the first time the courtroom has heard Ibarra's voice on the record since the trial began.

Minutes before this, prosecutors rested their case after calling 29 witnesses in just three days in the case that Haggard will decide, rather than a jury.

Laken Riley's sister, Lauren Phillips, broke down in tears and was comforted by the slain 22-year-old nursing student's roommates as a medical examiner testified about the gruesome details of her sibling's autopsy.

Lauren sat in the first row of the courtroom gallery next to Riley's three roommates -- who all testified Friday -- holding hands and linking arms as Dr. Michell DiMarco spoke about performing an autopsy on Riley's body the day after her Feb. 22 murder.

“She has combination of abrasions which are scrapes as well as contusions … as well as lacerations," DiMarco said from the witness stand as the sister sobbed.

“Her cause of death is the combined effects of blunt-force trauma and asphyxia,” the medical examiner said of Riley.

DiMarco added that “homicide” was her manner of death. 

Riley's mom, dad and stepdad were noticeably absent during the ME's testimony. They have been present for the majority of the three days of trial so far but have been anguished through much of the testimony.

A chilling, minute-by-minute timeline revealed in court Tuesday shows Laken Riley's final text and phone call to her mother before her death -- and her relatives' frantic attempts to reach her after she goes missing:

8:55 a.m.: Riley sends a text message to her mom, Allyson Phillips, saying, "Good morning. About to go for a run if you're free to talk."

9:02 a.m.: Riley reads an incoming text message from another person.

9:03 a.m.: She makes her last phone call to her mom, who doesn't pick up.

9:03 a.m.: Her phone locks -- and it won't be unlocked again until law enforcement does so as part of the investigation.

9:11 a.m.: Riley activates the emergency function on her phone, dialing 911, but the call ends without her speaking.

9:12 a.m.: The 911 operator calls Riley back two times, but her phone isn't picked up.

9:24 a.m.: Riley's mother calls her without getting an answer.

9:37 a.m.: Phillips texts her daughter, "Call me back when you can.''

9:51 a.m.: Another call from Phillips to Riley goes unanswered.

9:53 a.m.: Phillips calls again, to no avail.

9:58 a.m.: The mom frantically texts her daughter, "You're making me nervous not answering while you're out running. Are you OK?"

11:04 a.m.: Phillips calls Riley again. No answer.

11:12 a.m.: The mom calls again, no pick-up.

11:15 a.m.: Riley's mom calls again, no answer.

11:19 a.m.: Riley's sister calls her, no answer.

11:47 a.m.: The scared mom now texts, "Please call me, I'm worried sick about you.''

12:07 p.m.: Phillips calls again, no one picks up.

12:20 p.m.: Riley's stepdad calls her, no answer.

12:38 p.m.: Cops find Riley's lifeless body near the running trail where she went for her morning jog.

Laken Riley's mom, Allyson Phillips, wept in court as her 22-year-old daughter's last text message to her — asking to chat on the phone during her jog — was read aloud by a witness Tuesday.

"Good morning, about to go for a run. Are you free to talk?" the Georgia nursing student texted her mom before calling her at 9:03 a.m. on Feb. 22 — minutes before illegal migrant and Tren de Aragua prison-gang member Jose Ibarra allegedly attacked her.

Phillips missed what would be her daughter's final phone call.

Phillips put her hands over her eyes, crying as Riley's aunt comforted her in the courtroom gallery while Sgt. Sophie Raboud — with the University of Georgia Police Department — read out the messages.

Phillips texted Riley back at 9:37 a.m. — roughly 9 minutes after Riley died — saying, "Call me when you can."

The mom's ensuing text messages started to become increasingly alarmed when she received no response.

She texted her daughter at 9:57 a.m. saying: "You are making me nervous not answering while you are out running. Hope you are OK."

"Please call me. I am worried sick about you," the mom later texts.

Phillips also called her daughter several times, to no avail.

The mother has openly cried during the trial, including when seeing photos of Ibarra's arm after the slaying — allegedly scratched by her daughter as she fought for her life.

Accused murderer Jose Ibarra could allegedly be seen stalking another woman's apartment on and off for roughly an hour before Laken Riley was murdered, according to surveillance footage.

In the video, Ibarra can be seen going up to a door of the apartment of Tejaswi Stamilmnai Saraswathi, 24, a student at the University of Georgia, around 7:01 a.m., prosecutors said.

Ibarra then allegedly approaches her apartment door another six times and opens the screen door twice, the video shows.

Ibarra proceeds to a wooded area, then to a sports field and eventually comes back around 7:50 a.m. to Saraswathi's apartment door, prosecutors said.

Around 7:54 a.m., he can allegedly be seen on the video "ducking down" before leaving.

The footage was played during the testimony of Sgt. Sophie Raboud, who works with the University of Georgia Police Department.

"He's going south, toward the ... fields, and here he disappears into the woods," Raboud said of Ibarra leaving Saraswathi's apartment site for good that morning.

On Monday, Saraswathi testified she was in the shower when she heard someone "fidgeting" with her door. She went to the door to ask who it was, and the person fled, she testified.

In addition to murder charges, Ibarra faces a Peeping Tom charge related to his attempts to get into Saraswathi's apartment.

He is accused of hunting down and brutally killing Riley by 9:30 a.m. that same day.

Surveillance footage of Laken Riley running on a trail moments before Jose Ibarra allegedly attacked and killed her was played during his trial Tuesday morning, causing multiple people in the courtroom gallery to burst into sobs.

The footage was from 9:05 a.m. Feb. 22, just minutes before the Venezuelan illegal immigrant is accused of fatally beating and asphyxiating her.

Riley's mom, Allyson Phillips, began shaking and sobbing as others could be heard weeping in the courtroom.

The three roommates who lived with Riley and who testified Friday were also crying as the video was played.

Laken Riley's family arrived at the Athens-Clarke County Courthouse on Tuesday for the third day of her murder trial.

Illegal immigrant and Tren de Aragua gang member Jose Ibarra is accused of killing the Georgia nursing student in February.

Riley's mom, Allyson Phillips, and dad, John Riley, can be seen outside the courthouse.

The trial of Laken Riley's accused killer wrapped for the day after prosecutors called 11 witnesses Monday, the second day of trial, bringing the total witness count to 20.

Prosecutors told the judge they only have roughly a half-day's worth left of witness testimony Tuesday.

Trial is set to pick back up at 8:30 a.m.

Witness Sally Kirklewski testified she was out running the morning of Laken Riley's murder when she saw a person standing "really, really still" on the trail near where the nursing student's body was later found.

Kirklewski, an avid runner, said that when she went out for her jog that day, she saw "a number of" University of Georgia cop cars out, which got her "a little on edge."

She overheard the extra police presence was because of "suspicious activity."

Then on the trail around 8:24 a.m., she passed "a person who appeared to be a man" wearing a dark hat, jacket and other clothing matching what murder suspect Jose Ibarra was wearing when he allegedly carried out the brutal slaying.

Riley was attacked at 9:10 a.m. and dead by 9:28 a.m., according to testimony.

"I was a little worried," Kirklewski said of passing the person.

"They were really, really still," she said.

Laken Riley's mom, Allyson Phillips, broke down when a cop who analyzed the 22-year-old Georgia nursing student's heart-rate data testified about the moment her heart stopped beating.

Officer Wesley Durkit — with the University of Georgia Police Department — analyzed Riley's heart rate and location data from the Garmin watch she wore as she went out on her jog and during Jose Ibarra's alleged attack.

The watch showed that Riley halted her run, coming to a complete stop, at 9:10 a.m. and that her heart rate stopped at 9:28 a.m., Durkit testified.

The statement caused Phillips — who has been visibly emotional throughout the first two days of trial — to once again break down sobbing.
