ORIGINAL REPORT: LAS VEGAS (FOX5) -- Las Vegas police are asking for the public's helping finding a suspect connected to an east valley homicide on Feb. 24.
According to Lt. Ray Spencer of the Las Vegas Metropolitan Police Department, detectives were investigating at 5650 E. Sahara Avenue, near Sloan Lane.
Spencer said about 8:11 p.m. on Feb. 24, officers were called to the apartment complex for "unknown trouble." When they arrived, they were met by a neighbor who said a woman in an upstairs apartment was screaming for help. The neighbor told police the woman was screaming "Why are you here? Why are you in my apartment?" The neighbor went inside and found the woman injured.
Spencer said the woman had multiple blunt-force injuries, but they weren't sure what weapon, if any, was used. The woman was transported to Sunrise Trauma where she later died.
Through the investigation, police found the suspect lives in an apartment directly below the woman.
"The investigation by the LVMPD Homicide Section indicates that the suspect lives in a nearby apartment where he was involved in an argument with another person," a release stated. "At one point point, the suspect went to the victim’s apartment and beat her to death."
The suspect, a 32-year-old Hispanic man, was involved in a domestic incident with his live-in girlfriend, Spencer said. During the incident, the man went upstairs to the woman's apartment, seemingly unprovoked, and killed her.
The woman killed was only identified by Spencer as a 63-year-old Black woman. The Clark County Coroner's Office will release her identity after next of kin has been notified.
Spencer said the girlfriend and her children were uninjured.
No arrests have been made in the case. This remains an active investigation.
