An argument over a flashlight near a homeless encampment in Mission Valley ended with the stabbing of a transient and the suspect still at large, according to police.
The 34-year-old victim was stabbed in his right hand and back in the argument, in the 2100 block of Fenton Parkway.
Good Samaritans helped him get to a nearby trolley stop, where they called police, Officer Robert Heims said.
Paramedics responded to the stabbing shortly after 6:30 p.m. Saturday and took the victim to a hospital with non-life threatening injuries, Heims said.
The suspect was described as a white male with a knife, 25 years old, 175-180 pounds, with short black hair and a goatee. He was wearing a white shirt and beige cargo shorts.
