FREDERICK, Md. — The mother of a baby girl who was fatally abused by the child’s father has been sentenced to a year in jail for failing to protect her daughter.

Twenty-one-year-old Jessica Peavy of Hopatcong, N.J., was sentenced Thursday. Peavy will also serve one year of supervised probation.

She pleaded guilty in September to second-degree child abuse stemming from the death of 2-month-old Lexi Zirinsky. The girl died last November when the family was living in Brunswick.

Twenty-six-year-old Jason Zirinsky is serving a 30-year sentence for child abuse resulting in death. Court records describe multiple injuries, inflicted over a number of weeks.
