Summary

The San Francisco Police Department said a multi-agency investigation using forensic and profiling techniques led to the arrest and confessions in three violent assaults along the Fourth Street corridor; the commission presented certificates of appreciation to FBI and local partners.

The San Francisco Police Commission on April 4 heard the chief's report on an investigation that led investigators from the San Francisco Police Department and federal and regional partners to arrest a suspect in three violent assault-and-robbery incidents along the Fourth Street corridor in 2011.

In his presentation, the chief described how investigators moved "from a grainy video, still photo of the suspect to a person of interest, to a DNA match, an arrest, and confessions to all 3" within about 30 days. He named the arrestee in the transcript as "Frederick Dozer Junior, a 32 year old San Francisco resident," and said the individual had been arraigned on a total of 26 felony counts, including attempted murder and robbery.

The chief repeatedly credited the FBI and Daly City Police Department for investigative support. He said SFPD requested FBI assistance to narrow the pool of suspects, and that FBI Special Agent Adrian Sparrow coordinated with agents in Quantico and daily communications with SFPD Sexual Violence Unit investigators. The department also recognized crime analyst Jennifer Scandarelli for database queries and pattern analysis that helped focus the investigation.

John Connell accepted a certificate of appreciation on behalf of the FBI representative present, and the commission publicly thanked the Daly City Police Department and FBI for their roles. "There is absolutely no way the San Francisco Police Department could have been able to pull it this off without their help," the chief said in the transcript.

Commissioners and the chief used the presentation to highlight interagency cooperation and to show how combining technology, forensic matches and investigative interviewing produced confessions and criminal charges. The commission presented certificates of appreciation to federal and local partners and to SFPD personnel involved in the case.

The commission did not take further formal action on the case during the meeting; the chief said investigators would provide more detailed follow-up outside the public meeting where appropriate.
