PHOENIX (AP) - A corruption case against a former Arizona sheriff's deputy accused of helping a cartel-connected heroin smuggling ring was formally dismissed after a key wiretap document in the case turned up missing.The dismissal of corruption charges on Tuesday against former sheriff's Deputy Alfredo Navarrette was expected after prosecutors took the blame last month for never filing a wiretap application with the court.
Navarrette was once a member of Sheriff Joe Arpaio's immigration squad.
The discovery of the missing document led prosecutor to seek the dismissal of charges against Navarrette and five others, including two other former sheriff's employees, detention officer Silvia Rios-Najera and detention officer Marcella Hernandez.
While his corruption charges were dismissed, Navarrette pleaded guilty Tuesday to a felony arson charge.
He admitted getting someone to set his car on fire in an insurance fraud scheme in 2010.
