A Long Island mother of three was found dead in a car in Suffolk County Saturday — and a suspect has been charged with her murder, according to cops.

Juliann Bachmann, 30, of Bellport, was found injured and unresponsive in a vehicle at the Speedway gas station in Yaphank just before 7:30 a.m. Saturday, according to the Suffolk County Police Department.

After police discovered her, Bachmann was rushed to the NYU Langone Hospital — Suffolk in Patchogue, where she later died.

About 12 hours later, cops arrested Michael McHenry, 40, also of Bellport, and charged him with second-degree murder.

He was nabbed just before 8:15 p.m. and held overnight, ahead of a scheduled arraignment on Sunday at First District Court in Central Islip.

No further information was given about Bachmann’s cause of death, or whether she knew McHenry.
