New, heartbreaking details emerged Thursday about the accused killer Glendale first responder and his slain wife, including lovey dovey video from their wedding — showing the pair smooching while wearing firefighter hats.

What seemed to be a joyful, loving 10-year marriage took a horrifying turn on Wednesday when Andrew Jimenez, 45, was arrested on murder charges after allegedly hacking his 46-year-old wife, Mayra, possibly with an ax.

In 2014, Andrew and Mayra exchanged vows surrounded by loved ones in an intimate ceremony that featured subtle tributes to his aspiring career, according to video posted online.

In the footage, Andrew is seen fastening Mayra’s firefighter hat, adjusting his own, and lovingly sharing a kiss.

Another clip posted on social media shows the firefighter breakdancing and doing the worm with friends in the middle of the dance floor.

Friends and family described the couple at the time as kind, funny Los Angeles Dodgers fans. Snapshots on Mayra’s Facebook page also depict the couple in happier times, including one image from June 2018 showing the pair smiling while posing with Vin Scully, the legendary sports broadcaster and iconic voice of the Dodgers.

Andrew started with the Glendale Fire Department in April 28, 2008, as a paramedic and eventually became a firefighter. Last January, he teamed up with a friend, Richard Rama, to launch a GoFundMe campaign to rally support for Los Angeles’ recovery after the devastating wildfires.

“Glendale Fire Department’s own, Firefighter Andrew Jimenez, aka “Tremer,” and I have started a fundraiser because many have approached wanting to make sure their donations are going towards people and organizations in need,” Rama wrote on the page, which raised $3,510 of its $4,000 goal.

Mayra was a beloved 1st- and 3rd-grade teacher with LAUSD at Wilshire Elementary School in Koreatown and a non-denominational ordained minister.

“I consider it an honor to officiate your wedding. I am here to make your day memorable and touching for everyone involved,” Mayra wrote in her official bio on a wedding website.

Karen Chacon, whose child was one of Mayra’s students, shared a heartfelt tribute to the teacher on Facebook following her shocking death.

“Today we grieve the loss of an amazing teacher — Mayra Jimenez — a woman who fought fiercely for her students and her coworkers, who made sure every child was seen, and who gave my daughter Sarah a voice,” wrote Chacon.

The couple lived in a multi-family home in the eclectic North Hollywood neighborhood.

At around 4 a.m. Wednesday, Andrew walked into the LAPD’s Northeast Community Police Station and asked for officers to do a welfare check on his wife, police said.

Cops found her lifeless, bloodied body with “blunt force trauma,” and sources told FOX11 that investigators believe she was bludgeoned to death with an ax.

Andrew Jimenez was then arrested and booked on a murder charge, with his bail set at $2 million.

His attorney, Jose Romero, said he had discovered a diary entry allegedly showing that his wife was cheating on him before the homicide, which left friends and family reeling.

“That was a, that was a shock to wake up to … there was never any inclination that there was anything wrong or any domestic issues. We never heard them arguing or anything,” neighbor Kelson Zell told The Post.

Zell noted that Mayra was not only his landlord but also owned the entire property complex in the 5000 block of Satsuma Avenue, and that any problems tenants had were quickly resolved by the couple.

Exclusive footage showed family members gathered outside the home Wednesday, distraught and comforting one another before a body bag was wheeled into a medical examiner’s van.

A floral wreath hung above the door, with the words: “There’s No Place Like Home.”
