TRENTON, N.J. (AP) — The New Jersey attorney general's office says a grand jury has decided against filing criminal charges in the death of a Delaware man shot and killed by a state trooper last year at a New Jersey turnpike service area.

Officials said one of five troopers on an undercover narcotics operation at the Molly Pitcher Service Area in March saw 46-year-old Christopher Pizzichetta, of Lewes, apparently "shooting up" heroin. Authorities said he struck two of the troopers' vehicles while trying to flee in his pickup truck and sped directly toward a trooper on foot who then opened fire. Authorities reported finding a syringe and heroin in the pickup.

The attorney general's office said Wednesday that the grand jury concluded its deliberations Jan. 10 and decided against indicting the trooper who fired.
