San Francisco police on Wednesday said they arrested a 30-year-old man after a Muni passenger and Southern California native was killed in an attack they are calling "random" and "unprovoked." Cheryl Hurd has the latest from San Francisco.
The suspect in a seemingly random fatal shooting in San Francisco's Ingleside Heights neighborhood on Monday had threatened others earlier in the evening, and appeared to be "hunting" for a victim, District Attorney George Gascon said Friday.
Nikhom Thephakaysone, 30, allegedly held a gun to another man's back at a Muni stop near San Francisco State University earlier in the evening on the same day the murder of 20-year-old Justin Valdez occurred, Gascon said.
Witnesses to the murder and surveillance footage helped lead police to Thephakaysone at his home in the 200 block of Lobos Street, where he lives with his mother, stepfather and sister, according to police. Police found two assault rifles there, mcclane as well as knives, survival gear and around $20,000 cash in Thephakaysone's possession.
