A woman accused of shooting a man outside a Kent Starbucks on Tuesday afternoon turned herself in to Tacoma police about an hour after the shooting, police said.

Kent police spokesman Cmdr. Jarod Kasner said that officers were called to the coffee shop in a strip mall at Southeast 208th Street and 107th Avenue Southeast, on Kent’s East Hill, around 12:21 p.m.

They found a man lying in the parking lot with a gunshot wound to the head, Kasner said. “He suffered life-threatening injuries.”

The accused woman took off running after the shooting, Kasner said. It’s unclear how she got to Tacoma.

Mike Tyler, on a break from his sales job, said he was parked in a shady spot outside the Starbucks smoking a cigarette with his car windows down when he heard a “pop.”

“It sounded like kids playing with firecrackers,” Tyler said. But Tyler looked up and saw a man standing just feet away, at the front door of the coffee shop, clutching his bloody left cheek.

Tyler, a former soldier, hopped out of his car and yelled at strangers to grab towels and gloves.

“I walked over to him and compressed his wounds,” Tyler said on Tuesday afternoon, standing outside the crime-scene tape surrounding the strip mall where the shooting occurred.

Desperate to keep the wounded man conscious, Tyler engaged him in conversation. He said the man told him that he had been shot by his girlfriend.

Kasner said investigators are looking into the relationship between the man and the woman. He said the victim is at Harborview Medical Center in Seattle.
