The father of Boston Celtics rookie Tremont Waters was found dead in a West Haven, Connecticut, hotel on Thursday, according to police.

The medical examiner's office on Friday ruled that Ed Waters' death was a suicide.

Waters, 49, was found dead by police around noon Thursday after they responded to a report of an injured or ill person.

Tremont Waters, a point guard at LSU, was drafted in the second round (No. 51 overall) by the Celtics in last month's draft. He was averaging 10 points and 5.3 assists in four games during the Las Vegas Summer League. The Celtics do not have a summer league game scheduled for Friday.
