RALEIGH - The three-month hunt for a New Jersey murder suspect -- accused in the dumb-bell beating of a divorced mother of two -- has ended in Raleigh.

Raleigh police Friday arrested Demetrius M. Diaz-Bridges, 19, who was wanted in the Jan. 30 killing of Elizabeth O'Brien in Jefferson Township, N.J., about 50 miles northeast of New York City.

Diaz-Bridges is alleged to have beaten O'Brien with a hand weight, police reports say.

O'Brien, 49, died of blunt force trauma to the face and head, according to New Jersey news reports. She was discovered by police on the evening of Jan. 30. Police had been called to the scene by the victim's sons, The Daily Record of Morristown, N.J., reported at the time.

Morris County, N.J., investigators did not return calls Saturday. The case was the county's "No. 1 investigative priority," Morris County Prosecutor Robert A. Bianchi told the newspaper last month.

Diaz-Bridges -- who once lived on the same Jefferson Township street as O'Brien -- had recently been living at 1412 Brookside Drive in central Raleigh, police records show.

Raleigh's fugitive squad located him in Raleigh and arrested him without incident, police spokesman Jim Sughrue said.

It was unclear late Saturday why he was in Raleigh.

Diaz-Bridges was charged locally as a fugitive, based on New Jersey murder and weapon-possession warrants.

He was being held in a Wake County jail without bail and is scheduled to appear in District Court on Monday morning.
