A Facebook event page created for the vigil showed more than 5,000 people attending the event, at the Lake Merritt Pergola in Oakland.

Attendees posted photos online of mourners gathering around memorials dedicated to the victims.

Officials released the names of 10 more victims of the blaze on Monday.

Of the 36 victims, 22 have been positively identified, and their families have been notified, the city said in a statement. An additional 10 victims have been tentatively identified, and three victims need scientific identification. Three of the victims were from outside the country, from Finland, South Korea and Guatemala.

The Alameda County District Attorney's Office has launched a criminal investigation into the incident. Investigators are trying to determine whether there was criminal liability, and if so, who was responsible, said county District Attorney Nancy O'Malley.
