KALAMAZOO, Mich. (AP) — A man charged with killing six people during a series of apparently random shootings is returning to a southwestern Michigan court for a hearing on his mental competency.

The criminal case against Jason Dalton has been on hold for weeks while experts determine whether he can assist his lawyer. Michigan State Police say he’s been found competent. A court hearing in Kalamazoo is scheduled for Friday.

The exam wasn’t intended to determine whether Dalton was insane at the time of the Feb. 20 shootings. That’s a separate matter.

Dalton is charged with murder and attempted murder. Police say the 45-year-old man shot people outside an apartment building, a restaurant and a car dealership in between driving for Uber.

Two victims survived.
