According to Baltimore City Police, Damon Alexander went to the Stop One Grocery & Deli on Garrison Boulevard Nov. 30 with a purpose, to kill. The 27-year-old is the lone gunman who opened fire on a group of six people standing outside the store around 6 p.m. that night, police said.
The graphic and cold hearted killings were all caught on camera. Surveillance video showed how Alexander unexpectedly walked from the side of the building and started firing his handgun.
"Bam, bam, bam, bam, boom, boom, boom, it sound like something banging in the wall,” said store owner Mike Issa.
He was back in the office when bullets went flying. People inside the shop ran and ducked for cover.
In all, six people were shot. Police said four of them were Alexander’s targets, and he made sure two of those marks were dead before he ran off; 23-year-old Davon Dozier and 29-year-old Troy Smothers.
"This killer has killed before, there's no doubt about it, and the ease at which he pulled the trigger convinces me of that,” said Baltimore City Police Commissioner Kevin Davis.
Police said Alexander is member of the notorious Black Guerilla Family gang, and was already on probation for theft and buying a stolen firearm.
Officials believe the double fatal shooting is connected to at least one other recent murder in the area.
"We know that this case is an act of retaliatory violence in reference to another violent incident that occurred just in that same area," Davis said.
The cycle of payback killings in the city bring challenges for detectives because witnesses don't want to cooperate.
The day after the brutal shooting, detectives and police cadets went door to door in the area handing out fliers and combing for evidence. The next day, they released the harrowing tape of the shooting. Police said tips that came in from the community helped officers ID and arrest on Alexander.
"Our Warrant Apprehension Taskforce had been working different avenues to locate him, and they were able to locate him this morning sleeping on a family member's couch," said Baltimore City Police Chief T.J. Smith.
Back at the Garrison Boulevard store, cards and mementos serve as a memorial for the two lives lost. One of the shop's owners said he knew Smothers from the time he was about 7 years old.
"I feel so sorry for his family, he have a nice family," Moses Jaber said.
He said he's glad Alexander is now behind bars, an accused killer facing multiple charges for the violent double murder and shooting.
