Lawyer: Family of man charged in shootings know no motive

KALAMAZOO, Mich. -- A lawyer for the family of a man charged in a deadly Michigan shooting rampage tells ABC's "Good Morning America" that he was acting depressed in the days before the shootings, but they know no motive for the killing of six people and injuring of two others.

Lawyer Paul Vlachos (vah-LOCK-us) says Jason Dalton, of Kalamazoo Township, was asked by his wife, Carole, why he was acting differently and he told her he was tired. Vlachos says Dalton was "a good father" and "well-liked."

The 45-year-old is in the Kalamazoo County jail. Police say he admitted to the Saturday shootings, but they haven't revealed a motive. They say Dalton was working as an Uber driver, picking up fares between three separate incidents.

Vlachos says Dalton's wife is in disbelief.

Jason Dalton's attorney, Eusebio Solis, declined to discuss the case Wednesday.
