More details were revealed Monday about the surprising death of singer Brad Delp.   Police say that Delp's fiancee Pamela Sullivan found the Boston frontman dead in their New Hampshire home Friday morning.

"She had last heard from him the night before…because she stayed out after work with some colleagues," said Lt. William Baldwin. "She tried that morning three times to get a hold of him, and could not, so she went home and [found] him."

The cause of Delp's death is still under investigation although authorities say they don't suspect foul play. No autopsy is scheduled, but the state medical examiner is awaiting toxicology test results.

Brad Delp was 55 years old.
