Meghan Mogensen, 27, of Silver Spring, was sentenced to one month in jail and is barred from making decisions about the care or euthanasia of any animal if she serves as an animal caretaker or manager of a zoo or sanctuary.

Under the terms of the deal, a second charge for possession of an animal euthanasia drug without a license was dropped.

Mogensen was found guilty on both charges in Fairfax County General District Court in September, but she appealed the convictions to the county’s circuit court. She entered her guilty plea there on Friday.

Rood later found the animal’s wet body in a trash bag in a dumpster. She testified she found the animal’s crate next to a spigot and a bucket of water and suspected Meghan Mogensen had drowned the animal.

A necropsy performed on the wallaby found signs consistent with drowning. And prosecutors said Mogensen tried to cover up the drowning by forging a euthanasia report.

Mogensen’s attorney did not return a call for comment, but he said at her September trial that she was acting out of compassion for the wallaby, which had suffered a serious injury and would likely not live. He contended she injected the wallaby with a drug, but did not drown it.
