Mr. Parineh, 64, was arrested in Sunnyvale at about 3 p.m. Thursday, June 17, and later booked into the Maguire Correctional Facility in Redwood City, according to a statement from the San Mateo County Sheriff's Office.
Mr. Parineh is the only suspect, Detective Sergeant Bryan Raffaelli told The Almanac.
Medics found Ms. Parineh dead in the couple's bedroom with no signs in the house of forced entry. She was 56 and had been shot several times, Lt. Ray Lunny said. Mr. Parineh told authorities that his wife had shot herself, police said.
After an autopsy, investigators dismissed the suicide allegation and determined that Ms. Parineh had been murdered. The evidence and other information discovered in the investigation led to Mr. Parineh being a prime suspect, Lt. Lunny said.
Anyone with information about the case is asked to contact Detective Hector Acosta at 363-4084 or Detective Saul Lopez at 363-4347. To make an anonymous report, call (800) 547-2700.
