Courthouse Shooting in Middletown Leaves Gunman Dead MIDDLETOWN, N.Y. (AP) - A man who was convicted last week of harassing the mayor's daughter was killed on Wednesday by security officers after he walked into a courthouse and started firing a 12-gauge shotgun, according to the authorities and court documents. The man, Timothy Mulqueen of Middletown, opened fire in the courthouse lobby about 9 a.m. Officers returned fire as people dove under desks and scrambled for the rear door, officials said. "He had more rounds for the shotgun, and had he made it past the officers, who knows what mayhem might have ensued," said David Bookstaver, a spokesman for the state office in charge of New York's local court system. It appears at this point that the officers may have saved countless lives. Mr. Mulqueen, 43, died at a hospital. One officer suffered a graze wound to the arm, and two others were treated for shock. The police and witnesses said Mr. Mulqueen rode a motorcycle downtown, approached City Hall at first, then ran to the courthouse in Middletown, a city of about 25,000 in Orange County, about 70 miles northwest of Midtown Manhattan. District Attorney Frank Phillips said that the investigation was continuing and that it was not immediately known how many shots had been fired. Mr. Mulqueen's motive was not immediately clear, but court records show he had been arrested on menacing, trespass and harassment charges after an encounter with a daughter of Mayor Joseph DeStefano at the mayor's home in August. The daughter, Nicole DeStefano, told the police she heard a "violent knocking" on her front door on the evening of Aug. 6 and answered it to find Mr. Mulqueen asking for her father. This person then got agitated after I told him my father was not home. This person started to make violent hand gestures and he began to yell at me," Ms. DeStefano told the police. On Feb. 1, Mr. Mulqueen was convicted on a harassment charge and fined $129. His lawyer did not return a call on Wednesday.
