Marcus Lumsdon, 36, pleaded no contest to two counts of murder in the deaths of Sabri Khaleq, 63, and Adnan Khalil, 48, clerks at the Port Five Star Food Mart on the corner of Blanche Ely Avenue and Northwest 15th Street. He also pleaded no contest to one count of possession of a weapon by a convicted felon and one count of bringing prohibited items into the Broward main jail, charges that were added to his record in 2016 when he was accused of hiding a shank, an improvised knife, in his socks while in custody.
