Authorities said a Hellertown, Northampton County, woman was under the influence of a veritable narcotic cocktail when they saw her pulling into a borough gas station Wednesday night.

Amanda Ann Antonucci then allegedly threatened to kill a police officer who initially approached her for driving with a suspended license. The 27-year-old is now facing charges of terroristic threats, driving under the influence, tampering with evidence, possession of drug paraphernalia and driving with a suspended license.

Hellertown police said Antonucci pulled up to a gas pump at Top Star Mobil, 1570 Main St., about 7:45 p.m. Wednesday. An officer approached her because he was aware she had a suspended license and eventually took her into custody after she allegedly failed field sobriety tests, according to court records.

While in the patrol car and a holding room at police headquarters, Antonucci allegedly yelled at an officer, “I’m going to (expletive) kill you” and “I’m going to have my boyfriend (expletive) kill you.” Police also watched as she allegedly removed a hypodermic needle hidden in her “groin area” and tried to throw it down a vent in the holding room, according to records.

Police said Antonucci admitted to using a combination of methamphetamine, heroin, Xanax and methadone before driving. District Judge Richard Yetter arraigned her Friday morning, setting bail at $30,000. He allowed a 10 percent cash option, if approved by Northampton County pre-trial services.

Antonucci, of Main Street, failed to post bail and was sent to Northampton County Prison to await a preliminary hearing tentatively scheduled for Oct. 3.
