A man was fatally stabbed at a property in the 21000 block of Elmwood Street near Brown Street in Mead Valley just before 7 p.m. Thursday, and within hours, Riverside County Sheriff's homicide detectives had identified a suspect. Ruben Altamirano Estrada, a 54-year-old Moreno Valley resident, was arrested without incident on Elmwood Street and now sits in custody on $1 million bail on suspicion of murder.

According to the official Riverside County Sheriff's Office press release, Perris Station deputies were dispatched at 6:59 p.m. Thursday to reports of an assault with a deadly weapon under case file #PC262390062. Patrol deputies arrived to find the victim on the ground suffering from injuries consistent with stab wounds, and paramedics attempted resuscitative measures, but the man died at the scene, according to MyNewsLA.com.
