Corrections officials failed to properly supervise parolee Phillip Garrido and missed opportunities to discover the girl he allegedly kidnapped and held in his backyard for 18 years, a report summary released Wednesday said.

The California Department of Corrections and Rehabilitation also failed to refer Garrido for a mental health assessment, according to the report by the state Inspector General's Office.

The summary said Garrido "committed numerous parole violations and that the department failed to properly supervise Garrido and missed numerous opportunities to discover his victims."

The department also failed to train parole agents to conduct parolee home visits, failed to properly supervise parole agents responsible for Garrido and failed to adequately classify Garrido, the summary said.

It did not delve into the details of the findings and did not explain how agents failed to supervise him. The office released the summary on its Web site and planned an afternoon news conference to release the full document.

The two-month inquiry was launched after Garrido and his wife were arrested for allegedly kidnapping Jaycee Dugard and holding her captive in his backyard.

Questions arose about how Garrido managed to keep Dugard hidden for so long despite being monitored by parole officers because of a previous rape conviction.

Recommendations for supervision
The office has said its report would include recommendations for improving parolee supervision statewide.
