The man accused of initiating the drug buy that led to the 2010 death of a Chandler, Ariz., police officer made a plea bargain with federal prosecutors four months earlier to avoid a long prison term, and worked as an informant for the U.S. Drug Enforcement Administration at some time prior to the deal erupting in gunfire.

But Chandler police did not know John H. Webber had been working with federal officials when they ran a “reverse sting” targeting a quarter-million dollars that Webber and his cohorts agreed to pay for 500 pounds of marijuana supplied by undercover officers. Had the deal gone down as planned, the police would have kept the money under Arizona’s forfeiture law.
After the marijuana was delivered, one of the suspects opened fire with an AK-74 rifle, mortally wounding Detective Carlos Ledesma, according to police reports. Two other undercover detectives were shot, and two suspects were killed during the shootout on West Maldonado Drive in south Phoenix, about 16 miles from the Chandler border.
Maricopa County prosecutors said in court motions related to the ongoing murder case that Webber had worked as an informant for the DEA. However, the agency had stopped using him by the time of the shootout, and he had no authority to initiate the drug deal that led to Ledesma’s death, prosecutors argue.
The Goldwater Institute detailed the events that led to the shooting, and the extensive use of reverse stings by Chandler police, in a report published in March. The agency raised about $3.2 million through forfeitures in the year prior to Ledesma’s death, more than $2.7 million of that from reverse stings, according to city and court records.
