There's a padlock on the front door, and the Quick Mart convenience store on Loch Hill Road in Baltimore County remains closed a week after the attack---captured by the store's surveillance system.
In the just-released footage, you see the suspect approach the clerk and begin stabbing him as he tries in vain to defend himself for 10 seconds.
"The suspect, for some unknown reason, came behind the counter, approached the victim and very viciously, brutally, repeatedly stabbed this guy," said Cpl. John Wachter of the Baltimore County Police Department.
The victim, suffering from life-threatening injuries, ultimately ran out the front door.
The attack happened shortly before 4 p.m. on Dec. 6 when the 39-year-old victim was working behind the counter at Quick Mart in the 6500 block of Loch Hill Road.
While police won't say the clerk was targeted, neighbors aren't so sure since the suspect didn't stick around long enough inside the store to take anything.
"That sounds targeted to me,” said Paul Dziwanowski who own a auto repair shop next to the convenience store, “Like I said, he's got lottery over there. He's got cigarettes and cash and stuff and none of that was taken. So use your imagination. What else could it have been?"
Others in the neighborhood had no idea a violent crime had occurred.
"I don't think the neighbors are even aware that the person was stabbed in his store," said Hassan Alaoui.
Whatever the motive might have been, it doesn't appear investigators are any closer to making an arrest now, than they were a week ago prompting the public release of the graphic attack captured on camera.
"We want to put out this video in hopes that it kind of stirs someone to action, to see what a horrible crime has been committed against this man," said Wachter.
Despite the severity of his wounds, police say doctors released the victim from a local hospital today.
