Two people were found shot to death at a home in Irvine on Tuesday, and a man was taken into custody in connection with the crime, police said.
At about 1 p.m. officers responded to a shooting call at 14972 Crystal Circle and found two adults who had been fatally shot, the Orange County Fire Authority reported.
The suspect, 37-year-old Nolan Pascal Pillay, was taken into custody on scene, according to Irvine police.
Police told KTLA the fatal shootings were an act of domestic violence.
The home is in close proximity to Greentree Elementary School, which was placed on a voluntary lockdown while police were assessing the scene, officials told KTLA.
Neighbors told KTLA a father and his two adult children live in the home.
Police confirmed that the victims and the suspect are related, but would not elaborate on the victims' identities.
No other information was immediately released.
Several neighbors said they were shocked to hear about what happened in the home.
The deaths were the first two homicides of the year for Irvine, which has been named "America's safest big city," the Los Angeles Times reported. The city had three homicides last year, the newspaper reported, citing police.
