Former Green Bay Packers quarterback and coach Bart Starr summoned deputies to a locked house in suburban Tampa and found the badly decomposed body of his 24-year-old son.

The remains of Bret Michael Starr were unrecognizable, said Hillsborough County sheriff's spokesman Jack Espinosa, adding that it took authorities more than four hours Thursday to make a positive identification.

The county medical examiner was conducting tests today to determine how he died.
