LYNN – A New Hampshire man with Lynn roots, who was accused of attempted murder of a police officer in 1993, was found murdered inside his pick-up truck Tuesday night.Thomas J. Enquist, Sr., 42, of 9 Woodhenge Circle, Londonderry, N.H., is said to have died of multiple gunshot wounds, according to New Hampshire Attorney General Michael A. Delaney’s Office.The Lynn Classical High graduate and former Shillington Avenue resident was found around 10:30 p.m. by the New Hampshire State Police after a passerby reported an abandoned Ford F-150 on Route 101 in Auburn.”The manner of his death was a homicide,” said a statement from the Attorney General’s Office.The exact whereabouts of where the shooting took place remains under investigation. No arrests have been made and police are asking anyone with information to call 603-271-3636.Enquist’s lengthy criminal record includes the attempted first-degree murder of Manchester, N.H. patrolman Walter Feldhouse, numerous burglaries, drug and assault convictions, including a 1986 beating and stoning of a Lynn man who was trying to help a woman who was being attacked.According to Daily Item archives, Enquist was sentenced to state prison for a minimum of 10 years for the attack on Feldhouse, where he is said to have hit the officer in the chest with a crowbar and grabbed his .357 Ruger revolver from his hand. The attack was the result of a daytime burglary of Gosselin’s Pharmacy in Manchester, where Feldhouse ran after Enquist, struggled with him and had the gun stolen from him and pointed at his chest.Years after that incident, Enquist was charged with assaulting a teenager and his mother in Londonderry and was involved with the Lynn Breakers, a group of alleged burglars associated with the 2008 theft of $2.5 million in jewelry, including 27 New York Giants Super Bowl rings from an Attleboro factory.While Enquist was not charged in the large-scale burglary, he was determined to have been connected to other heists that the crew was suspected of, according to court documents.Enquist’s 20-year-old son, Thomas Jr. turned himself in to police in October on burglary charges.
