Shooting deemed murder-suicide in Boilingbrook (VIDEO)

Police have identified the two people killed at a workplace shooting in southwest suburban Bolingbrook, located just outside of Chicago, that triggered a lockdown for area schools.

Police confirm it was a murder-suicide involving two men who share the same last name, but are not related. Both worked for different auto parts companies, but the motive in the shooting is unclear.

Degang Zhang and Xingling Zhang were found dead at YCB International, an automotive parts company located in an industrial area near Veterans Parkway and Remington around 9:30 a.m., police said.
