Christina Boomer and Mark LaMet at KNXV-TV in Phoenix discovered more than 400 sex crimes cases, many involving young children, were ignored by the Maricopa County Sheriff's Office. Detectives never interviewed victims, witnesses or potential suspects, despite having solid leads in most cases. In the City of El Mirage, AZ, 43 of 51 sex crimes cases handled by the MCSO SVU had not been worked at all or had minimal follow up conducted. When El Mirage Police went back to review the cases, most of the victims had moved and could not be reached. One day after the initial investigation aired, the MCSO admitted the problem was even bigger, having to reopen more than 500 cases county-wide. A follow up story revealed the Sergeant in charge of MCSO SVU cleared cases, even though no work had actually been done.
