Mobile Tracking Application Leads to Cell Phone Robbers’ Arrest
On September 27, 2012 San Francisco Police arrested two suspects in connection with a robbery which occurred on Duncan Street at Diamond Heights Boulevard at approximately 8:00 pm.
In this incident the victim was walking on Duncan Street when he was approached by the suspect (later Identified as Waldo Butler). Butler asked the victim for directions to a nearby grocery store. When the victim pointed towards the grocery store, he noticed another male (later Identified as Paris Brown) sitting inside a tan minivan parked in front of a driveway on Duncan Street. It was at this point when Butler grabbed the victim by his arm, pulled him closer and produced a semi-automatic handgun from his waistband and pointed it at the victim. Butler demanded the victim’s cell phone, wallet, and backpack. Butler then took the victims items and fled towards the tan minivan.
San Francisco Police Officers immediately arrived on scene and were able to use a mobile tracking application that the victim had installed on his cell phone. This tracking software was put to use as part of the Police Department's violence prevention strategy of Interrupt, Predict and Organize (IPO) which seeks to: interrupt violent crimes, to predict where retaliation may occur and prevent additional violence from occurring. This technology led officers to 7th Street and Market Street. Once officers saturated the area, they were able to locate the tan minivan used in the robbery (with two occupants sitting inside the vehicle) on Laskie Street at 7th Street. It was later determined that the two occupants were the suspects in the robbery. Officers located the victim’s property inside the vehicle as well as a loaded semi-automatic handgun. The presence of this phone tracking technology and the quick and coordinated response of police officers from several district stations led to the identity and arrest of the two suspects who were identified as: Waldo Butler, male, 21, of Vallejo, and Paris Brown, male, 25, of San Francisco.
Butler is currently charged with felony 2nd degree robbery, felony receiving known stolen property, felony conspiracy, felony carrying a loaded firearm to commit a felony, misdemeanor carrying a loaded firearm in a public place, misdemeanor carrying a concealed weapon, and misdemeanor carrying a concealed weapon in a vehicle.
Brown is currently charged with Felony 2nd Degree robbery, felony receiving known stolen property, felony conspiracy, and misdemeanor carrying a concealed weapon in a vehicle.
