A West Covina man was convicted Monday of murdering his wife's parents, who had traveled from China to visit their daughter and grandchildren.
Jurors also found true a special circumstance allegation of multiple murders against Caminero Wang, who is expected to be sentenced Nov. 8 to life in prison without the possibility of parole.
Wang, 45, has been held without bail since the April 13, 2016 for the shooting deaths of Aiping Diao and Shu Zhang, who were both 60 years old.
Officers went to the family's condominium in the 1300 block of East Oahu Avenue about 8:30 p.m. that day on a report of several gunshots and "the sounds of children screaming," police said.
Wang opened the door to officers and surrendered without incident.
Police found the victims dead of gunshot wounds and three youngsters -- ages 3, 6 and 8 -- hiding in a bathroom.
Authorities said Wang's wife was at work at the time of the attack.
Wang was arrested in March 2013 on suspicion of domestic violence, and El Monte police found 23 guns in a search of his home. The stash of weapons included a fully automatic M-16 rifle and a semi-automatic Chinese-made copy of an Ak-47 rifle called a Mak-90, according to the San Gabriel Valley Tribune.
