JACKSON TWP — Police suspect that an 8-month pregnant woman was high on drugs late Tuesday night while riding in a car with her boyfriend and the couple’s 2-year-old child. A search of the vehicle after a traffic stop near Route 19 and Interstate 79 turned up suspected heroin, marijuana, hypodermic needles and other contraband, Jackson Township police said. Emily R. Stallard, 30, and her boyfriend, Andrew J. McClellan, 29, both of Reno, Venango County, were arrested on child endangerment and felony drug charges. District Judge Sue Haggerty arraigned the defendants on charges and sent them to the Butler County Prison. Bail was set at $5,000 for Stallard and $10,000 for McClellan. Police said Stallard and McClellan, along with their young child, were passengers in a car that a patrol officer stopped for a broken taillight just before midnight Tuesday on Little Creek Road at I-79’s northbound on-ramp. The officer also learned that the driver, David H. London, had a suspended license. He gave police permission to search the vehicle, documents said. The officer immediately noticed a hypodermic needle and metal spoon between the front passenger seat, police said. McClellan allegedly admitted ownership of those items. In a rear passenger seats, the officer found a sandwich bag with suspected marijuana laying on top of Stallard’s purse. The officer looked in the purse and found a needle and spoon and an unmarked prescription pill bottle. The bottle, a police affidavit said, had three bags containing “sizable” rocks of suspected heroin. Stallard claimed to know nothing about the drugs. However, police said she showed “signs of impairment.” London also told investigators that he had seen Stallard “inject a substance on their way back from Beaver Falls (in Beaver County),” the affidavit said. Stallard and McClellan are both charged with possession with intent to deliver a controlled substance, child endangerment, and possession of a controlled substance, marijuana and drug paraphernalia. Hearings for the couple are Tuesday at the office of District Judge Wayne Seibel in Evans City. Following their arrests, the child was turned over to relatives, said Jackson Township police Chief Terry Seilhamer. He also noted that in addition to traffic tickets, London faces a criminal charge for possessing a prohibited offensive weapon. That weapon, Seilhamer said, was a large commando-style knife.
