Fogerson has not been charged, though a judge found probable cause to hold him after a Wednesday afternoon bail hearing. The rush charging deadline is Thursday.
Fogerson, who had been a fullback, is the younger brother of former UW football player Johri Fogerson, who was kicked off the UW team after police said he was caught with marijuana and ran from a State Patrol trooper in May 2011. The older Fogerson pleaded guilty to resisting arrest in that case and transferred to Central Washington University.
Both Fogersons played football at O'Dea High School in Seattle, and their mother is a Seattle police officer.
Police say Zacchery Fogerson approached the victim about 10:35 p.m. Monday near the school's communications building and stole her orange and black purse. Another student who was in the area immediately called UW police, and officers began a search.
Fogerson's Mercury Marquis was seen on a dead end street and stopped near McMahon Hall. Police recovered a silver handgun and orange and black purse from inside the Mercury, according to court documents.
The victim, who was not physically harmed, identified Fogerson as the man who robbed her. In a bulletin that went to students and staff the suspect was described only as a former UW student.
Johri Fogerson has pleaded not guilty in an ongoing assault case for allegedly breaking the jaw of a 15-year-old O'Dea High School student and football player whom he allegedly fought at the school last year. Contacted by police days after the incident, O'Dea Head Coach Monte Kohler admitted he'd heard about the purported assault and said he'd spoken to Fogerson, according to police. Kohler said he then told Fogerson he was no longer welcome at the football training sessions.
