Another novel idea: Man with gunshot wound staggers into police station, admits to 30 armed robberies

This would make a great first scene for a crime novel (via the Oakland Tribune):

Oakland man reports shooting, gets arrested in 30 armed robberies

OAKLAND -- Walter Sayles came to Oakland police headquarters Wednesday to talk about being shot at that day. Instead, he was arrested after admitting committing more than 30 armed robberies at businesses in Oakland, Hayward, San Leandro and other cities.

The 21-year-old Oakland resident initially called police about 5 a.m. Wednesday from the 9200 block of Cherry Street in East Oakland to report being shot at. He wasn't hit but was treated at a hospital for an unrelated injury.

Sayles asked to speak with investigators about the shooting, and an officer directed him to police headquarters. The officer advised investigators that Sayles wanted to provide information about the shooting but also told investigators that Sayles matched the suspect description from a recent armed robbery.

Sgt. Randy Wingate and Officer Leo Sanchez began asking Sayles about some recent robberies after talking to him about the shooting. Wingate said Sayles admitted his involvement in more than 30 armed robberies going back several months at gas stations, convenience stories, fast-food restaurants and some street robberies throughout Oakland, Hayward, San Leandro, Palo Alto and other cities.
