BELCAMP, Md. — A Belcamp woman has been charged with the murder of her three-year-old niece.

Maria Louellen Barlow went into cardiac arrest on June 3 at a home on Ashmead Square.

The Harford County Sheriff's Office says her death was the result of months of abuse.

Deputies first arrested 43-year-old Randolph James Mack, charging him with first and second degree murder.

Mack allegedly took Maria to the bathroom to talk with her about wetting her pants.

She ended up suffering internal organ damage and a fractured rib, and might have even been strangled.

Turns out Mack is the boyfriend of Maria's aunt and legal guardian, 41-year-old Barbara Ann Mumpower.

Despite knowing what happened, Mumpower didn't call police until eight-hours after Maria was beaten. She initially blamed Maria's nine-year-old brother for the injuries, but later confessed that Mack had asked her to say that.

Mumpower was taken into custody June 8, which would have been Maria's fourth birthday.

Anyone with more information on the case should call the Harford County Sheriff’s Office Criminal Investigations Division, at 443-409-3154 or Metro Crime Stoppers at 1-866-7Lockup.
