SAN FERNANDO (CNS) – A Simi Valley man has pleaded not guilty to a capital murder charge stemming from the shooting death of his girlfriend’s estranged wife next to her vehicle in Granada Hills last summer.

Javier Flores, 24, is charged with the July 22 slaying of Cheyenne Brown, 24, who was killed in the 16600 block of Chatsworth Street.

The murder charge includes the special circumstance allegation of lying in wait, along with allegations that he used a gun in the commission of the crime.

Prosecutors will decide later whether to seek the death penalty against Flores.

Authorities say Brown — the mother of a 2-year-old daughter — was gunned down outside her home about 10:25 p.m. July 22.

“Brown had arrived home from work … when she was gunned down next to her vehicle,” according to an LAPD statement.  “Witnesses described a full-size truck fleeing the location after the shooting.”

Flores was arrested Sept. 12 by detectives from the Los Angeles Police Department’s Robbery-Homicide Division.

He remains in custody without bail while awaiting his next appearance Jan. 31 in a San Fernando courtroom.
