The sister of the man who killed four Lakewood police officers, LaTanya Clemmons, has been released from prison.

KOMO Radio reports she was released early Monday from the Washington state women's prison at Purdy.

She had been sentenced to five years for rendering criminal assistance to Darcus Allen, the getaway driver for Maurice Clemmons after he gunned down the officers in November 2009 at a coffee shop. She gave Allen $50 and drove him to a motel where he hid out.

LaTanya Clemmons was entitled to early release as a first-time nonviolent offender and for good behavior in prison.

A state appeals court threw out her conviction last month, saying there was no evidence she knew Allen was an accomplice. Pierce County Prosecutor Mark Lindquist says he's appealing that decision.
