A 3-year-old Florida boy was killed inside his home during a drive-by shooting that was an act of gang retaliation, sheriff officials and distraught relatives said.

The boy, Daquane James Felix Jr., was shot in the head inside a Pine Hills home late Tuesday as he played in the living room, his grandmother told WKMG.

“An evil person,” Felix’s grandmother, Veronica Felix, said when asked who shot her grandson. “A nasty person. Somebody with no heart. It’s scary. I can’t sleep in this house no more. It’s just scary.”

Felix said she had no idea why her family’s home was targeted by a shooter firing bullets into the front door, windows and a wall.

Daquane’s birthday was just 10 days prior to the deadly shooting.

“They killed my baby!” a woman at the home screamed late Tuesday after the shooting, according to the station.

No other injuries were reported and no details were known about a possible suspect, WKMG reports.

“If they got any conscience, they should turn themselves in because my grandbaby ain’t coming back no more and he was only 3,” Felix said. “He did not deserve this.”

Orange County Sheriff John Mina told reporters during a news conference Wednesday that investigators believe the shooting was an act of gang retaliation.

“There are some very violent gangs at work here in Orange County,” Mina said. “They’re heavily armed and not afraid to use violence. They don’t think twice about who they kill.”

Tuesday’s shooting came just one day after two other boys were shot at a Pine Hills home roughly three miles from where Daquane was killed, the Orlando Sentinel reports.

The shooting on Monday killed 14-year-old Joshua Atkinson and left an unidentified 15-year-old in critical condition, officials told the newspaper.

“But those are just two of the four drive-by shootings that have happened within this past week,” Mina said Wednesday while vowing to track down and arrest those responsible. “Each one, we believe, our detectives believe, is an act of gang retaliation.”
