A man was arrested and charged with murder Friday in the deaths of his wife and 13-year-old son in Valley Glen, the Los Angeles County District Attorney’s Office said.

The victims, Nataliya Glukhovskiy, 39, and Alexandr Glukhovskiy, 13, were found dead in their apartment on the 13800 block of Oxnard Boulevard on Dec. 26, 2018, the Los Angeles Police Department said.

Viktor Glukhovskiy, a civilian employee at LAPD Security Services Division, was not considered a suspect at the time, according to detectives.

The father and husband alerted authorities to the killings at around 11 p.m., saying he found them after arriving home from work, detectives said. He was described as being cooperative during interviews.

The LAPD continued investigating the case and Glukhovskiy was arrested more than a month later.

Authorities have not released information on what led investigators to arrest Glukhovskiy.

Glukhovskiy was charged with two counts of murder as well as special circumstance allegations of multiple murders, lying in wait and murder for financial gain, making him eligible for the death penalty, according to the DA’s office.

The criminal complaint said a shotgun was used in the killings, the DA’s office said.

The suspect was being held on a $2,000,000 bail.

Glukhovskiy’s arraignment is set for Feb. 5 at a Los Angeles court.

If convicted as charged, Glukhovskiy faces a possible maximum sentence of life in prison without the possibility of parole, or the death penalty. A decision will later be made on whether to seek the death penalty, the DA’s office said.

The Los Angeles Police Department, which is investigating the case, released a statement calling the killings “incredibly disturbing.”

“No individual is above the law and this Department will work feverishly to bring anyone who commits such a violent act to justice,” the LAPD’s statement said.
