Three of the victims are still at San Francisco General Hospital, one is in fair condition, another is in serious condition and the third one is in critical condition. According to officials their ages range from their 20s to their 40s, and they are all expected to survive.
The hit-and-run spree came to an end on 17th and Missouri in Potrero Hill, when the driver's blue Nissan Rogue crashed into another car and a utility pole. Police retrieved the suspect's vehicle and his wallet.
Witnesses saw the driver run away.
"He got out of his car and he ran out and I actually saw him run and everybody was like, 'Why didn't you tell anybody to run after him?' He just seemed like he was in a hurry, he was, like, not really running straight, he was more like, 'Oh my God, what did I just do?'" witness Angie Tabios said.
Police say three of the four men were taken to San Francisco General with non-life threatening injuries, while one was treated and released at the scene.
The driver covered about two miles and hit his four victims within six minutes just after 9:30 p.m. on Wednesday.
Police say they're treating this as an aggravated assault case.
"It certainly appeared to the witnesses that spoke to the officers that the white male suspect intended to hit these victims," SFPD Lt. Lynn Tomioka said.
"Such an odd, odd situation in all of my years here in San Francisco. I can't think of another incident quite like this," Renee Rivera from the San Francisco Bike Coalition said.
In the past, there have been tensions between San Francisco's drivers and bicyclists, but the San Francisco Bike Coalition says that's changed.
"In San Francisco, we've seen a huge increase in biking over the last few years, there are about 50 percent more people biking now than three years ago. At the same time, we are seeing fewer injury accidents happening to cyclists," Rivera said.
Police said they have three investigators on the case. They did a grid search of the neighborhood on Wednesday night but were successful.
Police hope to make an arrest in this case soon and if you have any information, please call the anonymous tipline at 415-575-4444.
