GREELEY, Colo. (AP) -- A man whose pickup crashed into a Visionworks store in the Greeley Mall, killing two, has been released from a hospital.

Police say 29-year-old Peter Wesley Lain of Evans may have a medical condition that caused the accident.

Witnesses have told police it appeared he was unconscious before the crash.

Thirty-two-year-old Kimberly Fletcher and 23-year-old Jennifer Hudgens were killed in the Saturday crash.

Hudgens was a store employee and Fletcher was a customer.

Fletcher's 9-year-old son, Zachary, was with her.

He was treated for glass injuries and was released.

Fletcher's husband, Tony, is a security guard at the mall and was among the first to respond to the crash.
