LAKEWOOD, Wash. -- A man who is the subject of an intense hunt may have important information about Adre'anna Jackson, the girl whose remains were found last week in Lakewood, police said.

Spencer Grant, 44, is wanted as a "potential witness" in the case but he is not a suspect because he was in jail when she disappeared Dec. 2 on her way to school, KIRO 7 Eyewitness News reported.

Grant was arrested July 13, 2005, on charges of burglary, drug possession and criminal trespass. He remained behind bars until Feb. 22, 2006.

"He has been in the area recently, and we hope he is still in the area," said Lakewood Police Chief Larry Saunders. "We're hoping with your help to get the word out that we're looking for him and he'll step up and come see us."

Police said Grant is a transient who is apparently familiar with the vacant lot where Adre'anna's remains were found.

Grant was described as 5 feet 10 inches tall, 165 pounds with black hair and brown eyes.

Saunders also said that the FBI has added $50,000 to a reward fund, making a total of $60,000 offered for information about her death.
