Investigators found 900 hours of videotaped traffic stops at the home of an Arizona sheriff’s deputy who committed suicide after his arrest on drug charges and are trying to determine if he was “shaking down” illegal immigrant drivers, court documents show. Ramon “Charley” Armendariz was found dead by deputies from the Maricopa County Sheriff’s Department on May 8, one day after failing to pick up an electronic monitoring device he had been ordered to wear following his arrest. During a search of his home a week earlier, investigators found the traffic stop videos, along with personal information of drivers with Hispanic surnames, according to documents unsealed in connection with a racial profiling case against the office run by controversial Sheriff Joe Arpaio.
