A judge said a man accused of helping the man who killed four Lakewood police officers will stay jailed for at least another month, reported KIRO Eyewitness News.

Pierce County investigators said Darcus Allen could face murder charges if there is evidence he helped Maurice Clemmons kill four police officers on Nov. 29.

The decision to keep Allen in jail will give investigators time to gather more evidence.

Allen has been in the Pierce county jail cell for a month waiting for prosecutors to decide his fate.

The 43-year-old man is under investigation on accusations of acting as the getaway driver for Clemmons the day he shot and killed the Lakewood police officers.

Allen is being held on a fugitive warrant from Arkansas and prosecutors want to wait until they have completed their investigation before sending him back east to face a parole violation.

"Whenever anybody is wanted on a warrant from another state, we file a fugitive detainer, we contact the other state, Arkansas, and they initiate a procedure called obtaining a governor's warrant which can easily take up to two or three months," said deputy Pierce County prosecutor Stephen Penner.

Allen was a cellmate of Clemmons when both were imprisoned in Arkansas. The fugitive warrant gives police and the prosecutor's office time they need to determine what role Allen may have played in the murders.

"We're reviewing reports right now to see if additional charges will be filed from the Lakewood officers' homicide," said Penner.

Allen will be back in court in late January.

He is one of seven people accused of helping Clemmons. All seven remain jailed.
