A burglary suspect wanted in four states remained holed up Thursday in a western Maryland motel, and doctors were standing by in case a woman believed to be his pregnant girlfriend gave birth, police said.

The standoff began around 10:30 p.m. Wednesday when state troopers and sheriff's deputies went to the America's Best Value Inn on Md. 522 in Hancock to arrest 26-year-old James A. Prevatt III, Maryland State police spokesman Greg Shipley said.

Shipley said Prevatt threatened to kill a woman in the room with him and any officers who tried to arrest him.

The woman is thought to be Prevatt's 21-year-old girlfriend, and Shipley said she is believed to be eight- to eight-and-a-half-months pregnant. Authorities don't know if Prevatt is the baby's father. A team of physicians from Johns Hopkins Hospital was standing by to handle any medical emergency, including childbirth, Shipley said.

Troopers and deputies evacuated about 12 of the 20 rooms in the one-story red brick motel where other guests were staying. Md. 522 was blocked in both directions near the motel, where a sign advertises room rates at $45 and up.

Prevatt is wanted in Maryland, South Carolina, Massachusetts and Virginia on burglary and larceny charges, Shipley said. Police did not know if he was armed, but Shipley said some of the burglaries involved the theft of firearms.

Police had telephone conversations with Prevatt overnight, but not consistently, they said.

Negotiations were continuing, Sof firearms.

Police had telephone conversations with Prevatt overnight, but not consistently, they said.

Negotiations were continuing, Shipley said, but "obviously, he does not want to come out and be arrested." He said that no shots had been fired, and police don't believe anyone is injured. He would not say whether police had spoken with the girlfriend.

Hancock is located in Maryland's mountainous western panhandle, squeezed between the Potomac River and the Pennsylvania border. The town has a population of about 1,700, according to the U.S. Census.

Joseph Michael, Washington County deputy state's attorney, said the only charges on record against Prevatt in Maryland stemmed from a July 2000 District Court warrant involving a burglary and the theft of electronic equipment at a home in Hagerstown.

Prevatt was serving time in prison in Massachusetts as late as February and was released after completing his prison term, Shipley said.

Five state police hostage negotiators were on the scene Thursday morning.

"We want it to end peacefully," Shipley said. "We want everyone to come out of this safely."
