Higgins was assaulted Sunday morning and was on life support at San Francisco General Hospital until Wednesday. He was brought to the hospital with no identification.
On Monday, the hospital released his picture to the media and later in the day he was identified with the help of a neighbor who saw the photo.
Before Higgins' life support system was removed Wednesday, friends and family stopped by the hospital to pay their respects.
On Wednesday, friends and family held an elaborate vigil at Duboce Park that was timed to end at 3:33 p.m., the time when Higgins would be removed from life support.
Police are still unsure of the circumstances that led to the attack on Higgins, but are reviewing video surveillance and other evidence in hopes of finding a suspect.
Correction: This story was updated Aug. 15 to correct the number of homicides in San Francisco this year. The number was incorrectly reported due to the fact that three possible recent homicides are pending review by the Medical Examiner’s Office. Officially, there have been 24 homicides so far this year.
