VACAVILLE — California police arrested a man for investigation of two killings after a caller reported seeing a social media livestream showing him armed inside an apartment and two women lying on the floor.

The Vacaville Police Department said officers went to the Rocky Hill Veterans Apartments at 12:42 a.m. Saturday in response to the call from a woman about the livestream.

“The video showed the man carrying a handgun and two women lying on the floor – not moving,” the department said in a Facebook post.

A SWAT team and negotiators were called in when officers found the man had barricaded himself in the apartment, the department said.

The rest of the building was evacuated after negotiations proved unsuccessful.

Officers made entry, using “distraction devices and chemical agents,” and captured the man after a brief struggle in which at Taser was used.

Raymond Michael Weber, 29, of Sacramento was booked into the Solano County Jail.

“Officers additionally found two women deceased inside of the apartment. The cause of their death remains under investigation and their identities are being withheld pending next-of-kin notifications,” the department said.

Online Solano County jail records show Weber was being held without bail on two counts of first-degree murder and was scheduled for a court appearance Tuesday. It was not immediately known if he had an attorney.
