Jacquline Montoya Rieux, 25

Jacquline Montoya Rieux, 25, was killed June 4 in the 11100 block of South Normandie Avenue in Westmont, according to Los Angeles County Sheriff’s Department detectives. 

Rieux’s 2-month-old son, Joshua, was also found dead at the scene.

Investigators have not released the cause of death or other details about the victims. 

Jacquline Rieux’s husband, Algernon Fitzgerald Rieux, a 26-year-old black man, was arrested on suspicion of two counts of murder June 5.  

The June 4 incident began at 8:12 a.m., when South Los Angeles Station deputies received a call about a baby not breathing, according to a Sheriff’s Department news release. 

When deputies arrived at the scene, they found a woman outside performing CPR on the infant. The woman told deputies that there was another person inside -- Jacquline Rieux -- who also needed help. 

Los Angeles County Fire Department paramedics pronounced the woman and the child dead at the scene, according to the news release. 

Algernon Rieux was identified as a suspect later that morning. Investigators described him as “bipolar, possibly suicidal and under the influence of methamphetamines” in a wanted poster issued that day. 

Algernon Rieux was found in the San Pedro area on June 5 and is being held in Los Angeles County Jail in lieu of $1,040,000 bail, according to the news release. 

Anyone with information is asked to call the Los Angeles County Sheriff’s Department’s Homicide Bureau at (323) 890-5500. Those wishing to remain anonymous should call Crime Stoppers at (800) 222-TIPS (8477).
