SMITHFIELD — The police in Douglas, Mass., said yesterday that they were awaiting positive identification of a body found Sunday in Wallum Lake, believed to be that of a missing Smithfield man.

Police Chief Patrick T. Foley of Douglas said that members of the Douglas Dive Rescue Team, assisted by colleagues from the Webster, Mass., dive team, found the body in 28 feet of water. The body was taken to Boston for identification.

Detective Lt. Michael C. Rheaume of the Smithfield police said that Lindsey Lima, girlfriend of Brian Silva, 34, of 11 Greenlake Drive, said that jewelry found on the body belonged to her fiancé.

There was nothing to indicate foul play, Rheaume said.

He said that Lima reported Silva missing on Thursday after she awoke and found him gone.

“He had left some time during the night, which was not unusual because sometimes he goes fishing,” Rheaume said, “but he hadn’t told her he was going out, so she was concerned.”

Silva had a small boat with him, but investigators said it was still in his parked truck, Rheaume said. His fishing gear, however, was missing.

After Lima reported Silva missing, she dialed his cell phone, which was answered by a stranger, Rheaume reported. That person turned out to be a homeowner who lives near Wallum Lake who exited his house and found Silva’s truck parked in his driveway without his permission.

The homeowner had thought the truck’s presence odd, and had summoned Douglas police. While he was waiting for officers to arrive, Rheaume said, he heard the cell phone ring and opened the unlocked vehicle and answered the phone.

Lima then went to the Douglas police to file a missing person report.

Rheaume said Smithfield police “checked every angle.” He said the police in Douglas were assisted by the Massachusetts State Police and the fish and game authorities at Wallum Lake, which extends into Burrillville.

He said the Douglas investigators used cadaver-sniffing dogs and side scan sonar to locate the body.
