SAN BERNARDINO >> Police on Monday continued investigating a shooting at a hookah lounge early Sunday morning that left one man dead and another wounded.

The second victim was initially listed in critical condition, but as of Monday morning had transitioned to good condition, said San Bernardino police Sgt. Emil Kokesh.

Samuel Smith, 23, of San Bernardino, died at the hospital from gunshot wounds, Lt. Dario Robinson said.

Smith had no criminal record and the motive for the shooting was still unknown as of Monday morning, Kokesh said.

“We have some more follow-up work to do,” he said.

The shooting was reported at 12:39 a.m. at Cleopatra Hookah Lounge, 1050 W. Kendall Drive. The victims went to St. Bernardine Medical Center, where hospital staff called police, Robinson said.

Numerous witnesses were interviewed and evidence was collected at the scene. Officials believe there are additional witnesses who have not yet been identified or contacted, police said in a news release.

A man who picked up the phone Monday at the number listed for the lounge said the incident happened within a matter of seconds, after a man near a dumpster opened fire with a pistol.

There was no apparent reason for the incident — no argument, no fight — the man said, before the phone line disconnected.

He said the lounge was set to close at 2 a.m., but that about 50 people were enjoying the evening.

The place had scuffles every now and then, he said, adding the business would likely be closed for at least a day until more is known about the shooter.

That said, he was concerned about the future of the business, which caters to a younger crowd from the area and has a casual environment in which everyone knows each other.

“I’m pretty sure I’m closing,” he said. “I got shot at. I got three kids.”

Repeated attempts to call the man back went unanswered.

The investigation is ongoing. Anyone with information regarding this incident can contact Detective Al Tello at 909-384-5747 or Sgt. Emil Kokesh at 909-384-5613.
