Deputies from the Moreno Valley Sheriff’s Station responded to the 15000 block of Rio Grande Drive at 1:19 p.m., after receiving the report of an assault with a deadly weapon, Riverside Sheriff’s Sergeant Ed Baeza said after the shooting.

When deputies arrived they found the victim, an 18-year-old, woman, suffering from multiple gunshot wounds. They also located a 21-year-old man, “suffering from a self-inflicted gunshot wound,” explained Baeza.

In an updated release, Baeza later identified the suspect as Damion Raymond Gibson, a resident of Moreno Valley.

Both subjects were transported to nearby hospitals for treatment of their gunshot wounds, according to Baeza; who said, “The victim remains in the hospital receiving further care.”

Investigators responded to the scene and assumed the investigation, with assistance from members of the department’s Forensic Services Unit.

During their subsequent investigation, officials received information that Gibson and the victim had been arguing just prior to the shooting.

After shooting the victim multiple times, Gibson turned the gun on himself.

“Our investigation revealed that the male suspect shot himself outside of the victim’s residence,” said Baeza.

Based on their investigation, officials arrested Gibson at Riverside University Health Care System Medical Center and he has since been booked into the Robert Presley Detention Center’s Medical Unit, where he is continuing to receive medical treatment for his self-inflicted gunshot wound.

Online jail records indicate Gibson was booked on charges of shooting at an inhabited dwelling and attempted murder and his bail has been set at $1 million dollars.
