Lancaster County Prison officials are dealing with quite the unique dilemma: twin sisters — with nearly identical names.

Lisa Rose Trout and Liza Rose Trout, both 29, are inmates at the prison, locked up for separate crimes.

Lisa Rose Trout was jailed Wednesday for endangering her 22-month-old child after witnesses reported she was haphazardly pushing the child around Elizabethtown while “extremely intoxicated,” an affidavit shows.

Witnesses told police Trout tipped the toddler’s stroller onto its side and left the child alone for several minutes on Tuesday evening. Police reported that Trout was talking to herself and picking “imaginery items” off the ground.

Liza Rose Trout has been locked up since Jan. 31, records show, for a probation violation and pending DUI charge, her third since 2009.

Prison officials said the Elizabethtown twins will certainly not share a cell, but could be housed on the same block, due to limited space.

“They won't be housed together just because they are family,” said Tammy Moyer, the prison’s director of administration. “But we have limited options with female housing, (so) they might be on the same block.”

While housing twin siblings isn’t unheard of, Moyer said she couldn’t recall such an occasion recently.

At least not since 2010, prison officials said, when the Trout sisters also were at Lancaster County Prison simultaneously.

“We will definitely flag their files since they are identical twins,” Moyer said. “We do the same if we have inmates with very similar names, which in this case, we have both.”

Lisa Trout’s boyfriend took over care of the child after she was arrested.

Elizabethtown police Officer Alexander Leonard describes the incident this way in an arrest affidavit:

Officers were dispatched to East Park Street for reports of a woman stumbling down a sidewalk, pushing a baby stroller.

Leonard spoke with Trout and noticed she had “very slurred speech” and trouble standing up. Also, Trout couldn’t keep still, making it apparent to the officer that she was intoxicated.

Witnesses later told police that Trout, while walking, almost tipped the stroller completely over and pushed the stroller into a street sign. She also left the child unattended on a sidewalk while she went into a home for a few minutes. That prompted one witnesses to stop Trout and the child until police arrived.

Trout’s boyfriend told police that she abuses her prescription medication.

Trout is charged with misdemeanor counts of endangering a child and reckless endangerment and summary counts of public intoxication and disorderly conduct.
