Debra Cobb, 37, was a woman going about an ordinary workday in Forestville, Maryland—until it ended in violence. Although you provided a different date, multiple published accounts place her death on June 13, 1994, when she was killed during a robbery at her workplace in an office plaza.
Investigators quickly centered on a man who didn’t come from the shadows of some far-off place, but from the same cluster of offices Cobb moved through as part of her routine.
The suspect, Alexander Wayne Watson Jr., worked in the same office plaza, and police arrested him not long after the killing.
The case did not stretch into years of unanswered questions in the way so many workplace murders do. Watson ultimately pleaded guilty to first-degree murder, later tying his actions to an addiction to crack cocaine. In December 1994, he received a life sentence without the possibility of parole and was sent into the Maryland prison system, while Cobb’s name became another entry in the long ledger of lives cut short for what was taken in a robbery.
Even after the conviction, the story around Watson didn’t stay confined to that one day in Forestville. In a letter written before his sentencing in Cobb’s case, he described the killing as “a terrible mistake” and again blamed crack cocaine, asking a judge for leniency—words that couldn’t rewind what had already happened.
Years later, advances in DNA technology and cold-case work would broaden the shadow cast by Cobb’s murder. Authorities linked Watson by DNA to three older killings in Anne Arundel County, and in 2004 he was charged in those cases; by 2007 he pleaded guilty to avoid the possibility of a death sentence, receiving additional life terms. Cobb’s murder remained the crime that first put him away, but it also became the doorway through which investigators eventually identified him as responsible for other deaths as well.
