LOS ANGELES (News Nation/KTLA) — A Los Angeles police officer who was an expectant father of twins died Friday after battling coronavirus, officials said.

Police Officer II Valentin “Val” Martinez, who worked in the Mission division in the San Fernando Valley, is the Los Angeles Police Department’s first sworn officer to die after contracting the virus, but the second employee to succumb to the deadly respiratory illness.

“Officer Martinez passed away after a long, courageous battle with COVID-19,” Chief Michel Moore said in an email to employees obtained by News Nation affiliate KTLA.

The 45-year-old is survived by his domestic partner, who is 20 weeks pregnant with twins, his mother and siblings, officials said.

“Our hearts and prayers go out to his loved ones, friends, and his Mission Area family as they grieve the loss of a fallen hero,” Moore’s email read. “I am authorizing the wearing of the mourning band in honor of Officer Martinez.”

In a statement, the Los Angeles Police Protective League also sent love and “unwavering support” to Martinez’s family.

“He was a hero lost way too early in life,” the statement read.

No further details about the officer’s battle with the virus have been released.

Erica McAdoo, who worked as a senior detention officer at LAPD’s Metropolitan Detention Center in downtown Los Angeles, died July 3 after a weekslong battle with COVID-19.

As of Wednesday, the LAPD had a total of 437 employees who had tested positive for coronavirus, officials said. In addition, 254 employees were self-isolating and recovering after being exposed, and 237 had returned to work.
