Hours before police arrested a Wyoming woman suspected of tossing her infant daughter into a ditch, a sheriff’s deputy cited her for allegedly breaking into a nearby car.

Lillian Jeffrey, 31, was cited for rummaging through a purse in a parked car at 9:15 on Friday night, according to court documents.

She was arrested four hours later on suspicion of throwing her 2-month-old daughter into a ditch near a truck stop less than a third of a mile from the site of the citation. Officers believe she may have been high on drugs at the time.

A Laramie County Sheriff’s Office captain said early Monday afternoon that Jeffrey had been cited for the crime, but did not respond to multiple follow-up calls.

Officers responded to a suspicious activity call at about 1:15 a.m. on Saturday at a Love’s Travel Stop service station. Police said Jeffrey was in the driver’s seat of a vehicle, acting erratically. The windows were down with two car seats in the vehicle but only one child, a 4-year-old, was inside. That child was taken into protective custody.

Authorities say they suspect Jeffrey may have been high at the time and made nonsensical statements when officers arrived.

The baby was found injured in a ditch and taken to Cheyenne Regional Medical Center, where she was airlifted to a Colorado hospital for further treatment.

A Cheyenne Police Department spokesman said Monday evening that the baby was still in the hospital.

“The baby is doing OK,” Officer Kevin Malatesta said. “Recovering.”

Jeffrey was still being held in Laramie County Detention Center on Monday.
