Essex man, Belcamp woman charged with murder in death of three-year-old Harford County girl

BELCAMP, MD—The aunt and guardian of a three-year-old girl who was murdered in Harford County last week has been arrested and charged.

On June 3, deputies with the Harford County Sheriff’s Office responded to the 1200-block of Ashmead Square in Belcamp for a report of a juvenile in cardiac arrest. Upon arrival, deputies located a small child in the living room, with medics already attempting life-saving efforts. The child, identified as Maria Louellen Barlow, was taken to  University of Maryland Upper Chesapeake Medical Center, where she was pronounced dead.

As a result of the ensuing investigation, Randolph James Mack, 43, of Essex, was charged with first- and second-degree murder, first- and second-degree assault, and child abuse.

The investigation continued, revealing a pattern of abuse conducted by both Mack and Maria’s aunt, Barbara Ann Mumpower, 41, of Belcamp, dating back to at least January 4, 2022. Mumpower was Maria’s guardian at the time of the abuse, and she was in the physical custody of both Mumpower and Mack at the time of her death. Mumpower and Mack were in a relationship at the time of the murder.

Mumpower has been charged with first-degree murder, child abuse, neglect of a minor, and accessory after the fact. Detectives arrested her without incident on June 8, on what would’ve been Maria’s fourth birthday. She was transported to the Harford County Detention Center, where she is being held without bail.

The investigation is ongoing. Anyone with information about this crime is asked to call Detective Moro with the Harford County Sheriff’s Office at 443-409-3154. Those who wish to remain anonymous, may report their information through Metro Crime Stoppers at 1-866-7LOCKUP.
