An Alabama mom who works as a paramedic has been arrested for allegedly providing alcohol and vapes to her child and his friends, investigators said Thursday.

The investigation began on Valentine’s Day when the Mobile County Sheriff’s Office was contacted about the reported behavior of a mother. The witness told investigators that the woman was providing alcohol and vaps and allowing children to use marijuana.

After weeks of investigation, Mobile County sheriff’s deputies arrested Jessica Ulmer, 42, and charged her with three counts of reckless endangerment.

Ulmer reportedly works as a certified paramedic for a Mobile area ambulance company. Investigators said Ulmer alsio administered shots for nausea and IV saline fluids to the teens, most of which were between 13 and 15 years old, investigators said.
