LAUREL, Md. - New information is emerging in the murder investigation of a mother and her baby daughter in a Laurel roominghouse on Tuesday.
Prince George's County Police have not named any suspects in the murders of Lisa Laverne Brown and her 9-month-old daughter, but police have located and questioned a man ordered by a court to stay away from Brown.
Police will not identify the man, but law enforcement sources say the man is Malik Samartaney and he had a long-term relationship with Lisa Brown's mother.
At times, Samartaney lived in the house with Brown, her baby, and her mother, sources say.
One of the possible motives being investigated is that the baby's crying prompted the killings, sources say.
Forensic testing is underway to determine whether physical evidence links Samartaney or anyone else to the murders.
On Tuesday afternoon, police found Brown, 22, and her 9-month-old daughter dead from gunshot wounds in an upstairs bedroom of the home where they lived on the 13700 block of Engleman Drive.
Brown's handwritten application for the peace order said that her mother's boyfriend "was drinking last night and got upset with me because he didn't want my mother to watch my daughter. We got into a verbal altercation, and he threw money in my face," The Washington Post reports.
There was no indication of a forced entry in the house, police say.
Samartaney has prior charges of domestic violence, but has never been convicted.
