The director of the Reston Zoo is scheduled to stand trial Friday on charges related to allegedly mistreating a sick wallaby.

Meghan Mogensen, 26, of Silver Spring, was arrested in June after a five-month investigation into the way the zoo was handling sick animals and administering euthanasia drugs, police said.

A tipster told police in January that the wallaby’s crate was found next to a five-gallon bucket of water and the wallaby’s wet body was found in a trashbag in a nearby dumpster, according to a search warrant.

Mogensen later told a Fairfax County animal control officer that she had euthanized the animal by injecting it with a drug used for the purpose, but the officer found no injection site on the wallaby’s body, according to the search warrant.

Another informant later alleged that Mogensen had a history of drowning sick animals at the zoo, according to the search warrant.

Investigators said they believe Mogensen received instructions on how to euthanize the wallaby from the zoo’s corporate director, according to the search warrant.

Mogensen was charged with animal cruelty and possession of a controlled substance. Both are misdemeanors. She will be appearing in Fairfax County General District Court around 10:45 a.m.

Mogensen’s attorney did not return a call for comment. The Reston Zoo declined to comment on the case.
