He is described as a Black/African American man, 5 feet 6 inches tall, about 185 pounds, with black hair, brown eyes, right-handed and wearing gold-framed eyeglasses.

On the day he disappeared Mark reportedly called his mother and said he was struggling emotionally and financially. When his mother drove from Chester, Pennsylvania, to check on him she found neither him nor his black 2003 GMC Yukon (Delaware plate PC478018). Witnesses later reported seeing a man drive onto the Commodore Barry Bridge, exit the vehicle and jump into the Delaware River; officers located Mark’s Yukon on the bridge with the keys inside. No body was recovered and he has remained classified as a missing person. The New Castle County Police Department is listed as the agency associated with the case.

Does anyone have information about Mark’s whereabouts around May 11 of 2009 or 2010, or recall seeing that Yukon on the Commodore Barry Bridge that morning?
