Jenny Sor, 40 [Updated]

Jenny Sor, a 40-year-old Asian woman, was shot and killed Tuesday, Jan. 19, in the 200 block of North Chandler Avenue in Monterey Park, authorities said.

Wenwa Chao, a 53-year-old Asian man and Sor's boyfriend, was also killed in the shooting. Chao and Sor were visiting a senior housing facility where Chao's father lived at the time of the shooting.

Detectives believe jealousy probably motivated the shooting, which happened just before 8 p.m. The alleged shooter, Richard Vithya Tauch, a 45-year-old man, was Sor's ex-boyfriend.

Tauch was taken into custody Wednesday, Jan. 20, around noon. He was booked for investigation of double murder and held in lieu of $1-million bail at the Monterey Park jail, said Lt. David Dolson.

"We don’t know the entire circumstances. But the suspect is the ex-boyfriend of the woman and the other victim is her new boyfriend," Dolson said. "We believe [the suspect] followed her into the place." Dolson said the suspect followed the female victim in through a glass patio door and sometime afterward shot the two victims.

Tauch, according to state licensing records, has a permit to carry a firearm while working as a security guard.

[Updated Jan. 28 at 11:50 a.m.: Tauch was originally identified as a black man, but his race is officially listed as "other" by law enforcement.]
