A Maryland mother was recently arrested and charged in connection with her infant daughter’s death, authorities say.

Accused of murder in the first degree and first-degree child abuse is Maya Marie-Iman Dennis, a 32-year-old individual as reported by the Harford County Sheriff’s Office.

The extremely young victim in the case has been identified as a five-and-a-half-month-old baby girl, Old Line State law enforcement say.

The investigation began while the child was still alive, on Dec. 29, according to a press release issued by the sheriff’s office.

The incident unfolded with a call from Child Protective Services, who were in the midst of their own inquiry at Johns Hopkins Pediatric Trauma Center.

Upon observing the extensive injuries sustained by the child, suspected to be indicative of child abuse, welfare authorities contacted the investigators, according to the sheriff’s office.

“Upon meeting with medical staff, Detectives learned that the baby had been brought to the hospital, by ambulance, presenting with multiple skull fractures, brain bleeds, a fractured leg, and numerous other life-threatening injuries,” according to the press release.

The investigation progressed apace.

Detectives requested, received, and executed a warrant to search the Dennis family’s residence on Mayberry Drive in Aberdeen – a small city located some 30 miles northwest of Baltimore.

At first, the picture seemed muddled or incongruous.

“Multiple interviews of potential witnesses and suspects were conducted resulting in inconsistent accounts of how the infant victim sustained her injuries,” the press release reads.

But, law enforcement claim, the signs eventually pointed one way.

Authorities did not say, however, when, exactly, the girl’s injuries are thought to have occurred. No motive or explanation for how the injuries occurred has been revealed either, as of this writing. The infant’s name also has yet to be released.

While the investigation progressed, the case took a turn.

“As the detectives continued searching for answers, the infant girl died from her injuries,” the press release explains.

Authorities say the accused mother later made “statements indicating she was responsible for the now fatal injuries.”

The defendant was arrested at the same hospital where her child was being treated on New Year’s Eve without incident.

Dennis is currently being detained in the Harford County Detention Center. She is slated for a bail and/or bond review on Jan. 2, court records show. A preliminary hearing also is scheduled for Jan. 30.

The investigation is said to be ongoing.
