A Southern California firefighter is currently in custody following allegations of brutally killing his wife with an ax and subsequently attempting a poorly executed cover-up, according to California authorities.

Andrew Jimenez, aged 45, was apprehended this week on charges of murder concerning the death of his 55-year-old wife, Mayra Jimenez, as reported by the Los Angeles Police Department.

The tragic event unfolded earlier in the week at the couple’s residence on Satsuma Avenue in North Hollywood, a neighborhood within the San Fernando Valley area of Los Angeles.

In the early hours of Wednesday morning, around 4 a.m., Jimenez, who was off-duty at the time, visited the LAPD’s Northeast Community Police Station in Glassell Park. He requested a welfare check on his wife, citing his inability to contact her, according to police statements.

Upon conducting the welfare check, officers were met with what was described as an “appalling” scene, according to law enforcement sources referenced by KTTV, a Los Angeles-based Fox television station.

Inside the home, authorities discovered Mayra Jimenez had been violently attacked and killed. An ax was located near her body, police reported.

Around 4:25 a.m., the defendant was questioned and eventually confessed to killing his wife, according to law enforcement.

The requested welfare check, in the end, apparently did little to convince investigators the defendant was not to blame.

“[The] investigation revealed that the victim and suspect were in a marital relationship and that this was an incident of domestic violence,” the LAPD said in a press release.

Friends and neighbors who knew the couple said the pair had never been in conflict before, according to Los Angeles television station KTLA.

“Such a violent crime, the extreme,” one neighbor told the TV station. “There’s never been any violence or domestic violence or signs of that at all. So, I’m really surprised.”

The couple had been married for 10 years, family members told local ABC affiliate KABC.

Before she died, Mayra Jimenez worked as a third-grade teacher at Wilshire Park Elementary in central Los Angeles. Described as a “caring educator,” the victim was also a union representative for United Teachers Los Angeles, KTLA reported.

The school subsequently released a statement:

We are heartbroken by this loss, and many of us are still processing this information, as we only just learned of it. Mrs. Jimenez was a beloved teacher, colleague, and friend, and she made a lasting impact on our school community and the students she served. Our thoughts are with Mrs. Jimenez’s family, loved ones and all who are grieving during this incredibly difficult time. We ask that the community respect the privacy of Mrs. Jimenez’s family during this difficult time.

While initial reports lacked any kind of details about a possible motive, an attorney for the defendant suggested romantic jealousy may have been the reason for the woman’s death.

“Our office is currently in contact with law enforcement regarding a diary of the decedent, apparently read moments before the homicide, that verified infidelity by the decedent,” Andrew Jimenez’s attorney told KTLA.

While investigators say the woman was killed via blunt force trauma injuries, police also removed two large rifles from the residence, KABC reported. It is unclear if any firearms were used in the murder.

“I could just hear them talk about how horrific it was…it was just bloody,” the Jimenezes’ neighbor told KABC.

The defendant has worked for the Glendale Fire Department since 2008 as a firefighter and paramedic. Andrew Jimenez had recently been promoted and was praised for his work during the Palisades fire, KTLA reported. He has since been placed on administrative leave.

“This is an extremely serious and deeply troubling matter. First and foremost, our hearts are with the victim’s family and loved ones, and we extend our sincere condolences as they grieve this tragic loss,” the fire department said in a statement. “Due to the active and ongoing nature of the investigation, the City of Glendale and the Glendale Fire Department are unable to provide additional comments at this time.”

Andrew Jimenez is currently being detained in the Los Angeles County Jail on $2 million bail, Los Angeles County Sheriff’s Office records show.
