Police say a gunman killed himself after fatally shooting one person and wounding five others around Gainesville.

Police say the gunman shot himself in his red pickup truck on Monday after he drove through the neighborhood picking off victims.

The gunman has been identified by relatives as 24-year-old Clifford Miller Jr., according to The Gainesville Sun.

The paper reports that Miller has a police record and a history of mental illness.

Gainesville police say they have no motive for the shooting.

"We have no idea right now, absolutely none. It appears to be random," Cpl. Tscharna Senn told The Gainesville Sun.

A police spokeswoman says the wounded were being treated at Shands Hospital. She says they had minor to critical injuries, but wouldn't give details.
