Police scoured surveillance video and interviewed witnesses Monday, hours after a brazen gunman fired into a crowded East Lake Street restaurant, killing one man and injuring three other people.
Neighbors were left rattled after the gunman walked up to the front windows of the La Que Buena at 1611 E. Lake St. around 1:30 a.m. Monday and opened fire. A 32-year-old man inside the restaurant was killed, and the others, aged 19, 22 and 30 were expected to survive.
"You really hate to hear that someone died. It wasn't directed at the neighborhood, apparently," said Steven Sandberg, who lives near the shooting scene and called the whole thing unsettling.
Police said the gunman fled and has not yet been found.
Investigators were looking into the possibility that the shooting was gang-related, Third Precinct Police Inspector Michael Sullivan said in a message e-mailed to the public Monday afternoon.
Police spokeswoman Cyndi Barrington said it did not appear to be a random act, a lone shooter is suspected and the motive is unknown. The names of the victims have not been released.
"The suspect approached the building from the outside and then shot into the restaurant," she said in a statement. "The suspect then fled the scene."
Numerous exterior video surveillance cameras are in the immediate area. Three video cameras are on the front of the restaurant, and two more are posted across the street, one at the Salvation Army worship and service center and another on the corner of Lake and 16th Avenue S.
