LOWELL, Mass., May 25 (UPI) -- A man who allegedly kidnapped his ex- wife at gunpoint from a women's shelter in Nashua, N.H., has been arrested at an apartment in Lowell, Mass., ending a frantic 24-hour effort to find the woman before she was killed. Police say Gary Collinge (coh-LINJE), 49, and Marguerite Eno, 46, were both ``OK'' when they were taken from the residence on the city's north side tonight. A special team of officers burst into the unit on First Street shortly after 10 p.m. after a nearly five-hour standoff with the gunman. Collinge, who has been arrested three times for assaulting his wife in the past two years, was held at the Lowell police station for arraignment Tuesday on kidnapping, weapons and other charges. Police said Eno was working a safe house for battered women she runs in Nashua Sunday night when Collinge walked in, pulled out a gun and forced her into his 1987 Ford Thunderbird after firing several shots into the air. Police say Collinge had recently lived in both Tyngsboro and Lowell, as well as Pelham, N.H., and investigators were keeping an eye on all three locations. Collinge recently spent 51 days in jail for violating a court restraining order to stay away from his ex-wife, and Boston television station WCVB, Channel 5, said Collinge had told a friend that he planned to kill his wife and himself after he got out.
