The death Tuesday night of a 7-week-old girl who was taken to the hospital with severe head injuries has been ruled a homicide, and her parents have been charged with first-degree murder, Baltimore County police said yesterday.
Amanda Lee Sennett, who was born Christmas Day, was pronounced dead at the Greater Baltimore Medical Center about 9:45 p.m. Tuesday, said Sgt. Stephen R. Doarnberger, a police spokesman.
Her parents, Deborah L. Sennett, 31, and Thomas G. Sennett, 33, were charged last night with first-degree murder. Police said they arrested Mrs. Sennett at her parents' home in Harford County about 7:30 p.m. Mr. Sennett turned himself in to police in Towson about 8 p.m., they said.
Both will have bail hearings today.
When police officers went to the baby's home in the 9700 block of Magledt Road in Parkville, they found Amanda's 16-month-old brother also suffering from injuries to the head.
The brother, Thomas Gordon Sennett Jr., was taken to St. Joseph Hospital, where he was reported in good condition.
When investigators questioned Mr. Sennett Tuesday, they said, he told them he did not know how his children had been injured. The Department of Social Services has been notified of both cases.
An assistant state medical examiner said the baby died of severe trauma to the head and ruled the death a homicide. An autopsy is continuing to determine when and how the injuries were inflicted.
There are no other children in the family, and police said they have no record of any calls for police assistance at the Sennett house.
