Jeffrey Stenroos, the former Los Angeles school police officer who staged his own shooting last year in a bizarre hoax that caused three schools to be locked down and forced closure of streets across the the western San Fernando Valley, will pay the city a lump sum of $309,000 in restitution, authorities said Monday.

In exchange for the restitution, Judge Richard Kirschner agreed to let Stenroos post bail from Los Angeles County jail pending the outcome of an appeal.

The lion's share of the payment was to compensate the city of Los Angeles for deploying more than 500 officers, plus traffic management workers. The restitution also will be discussed at a court hearing next month.

"It's highly unusual to receive such a large amount in a lump sum but we welcome receiving the money," said William Carter, chief deputy to City Atty. Carmen Trutanich. He said the money, raised by Stenroos' friends and family, is expected to be received by the city Wednesday.

Stenroos, 31, was convicted in September of planting false evidence, insurance fraud and other crimes. The sentence came after Stenroos underwent a 90-day psychological evaluation to assess whether he should go to prison or receive probation.

In December, Stenroos was sentenced to five years in county jail but Kirschner said he would have to serve only two years if he met the terms of his probation, which included completing 400 hours of community service.

The Jan. 19, 2011, hoax triggered a massive and costly manhunt for a fabricated assailant, and it brought a swath of the San Fernando Valley to a standstill for hours.
