Officials said Briscoe was part of a conspiracy to distribute heroin between March and October 2015. On May 27 of that year, in connection with the drug distribution, he allegedly tried to steal heroin from 37-year-old Jennifer Jeffrey, during which he fatally shot Jeffrey and her seven-year-old child.

The child was shot multiple times, including in the head and the mouth, according to the indictment.

“This case is nothing short of tragic. A mother and her child, who was believed to be a witness, were senselessly murdered by defendant Andre Briscoe,” said U.S. Attorney Erek L. Barron. “Let this conviction serve as a message to those who would take a life that the United States Attorney’s Office for the District of Maryland will prosecute anyone who harms, or attempts to harm, witnesses.”
