WHITE CLOUD, Mich. (WOOD) — Another plea that could bring new answers as police continue to investigate the 2004 murder of Amanda Lankey.
Marcus Wallis pleaded guilty on Monday to providing false information to a police officer.
A Newaygo County judge sentenced him to 60 days in the Newaygo County jail, which will be served on weekends. Wallis will also be required to take a polygraph regarding the Amanda Lankey investigation.
Amanda was 13 years old when she vanished from a friend’s house in White Cloud in June of 2004. Her body was found two weeks later in the Manistee National Forest. She died of blows to the head, according to an autopsy.
Marcus Wallis’ uncle, Cecil Wallis, committed suicide in 2011 while in jail, shortly after he was charged with sexually assaulting two other girls.
Cecil Wallis was never charged in Amanda’s death, but a detective working the case told Target 8 he thinks Wallis killed Amanda and that family members helped him get away with it.
Candace Baumgartner-Wallis, the sister of Cecil, was a White Cloud police officer at the time of the homicide. Last month, she pleaded guilty to one count of lying to detectives — a lie that had nothing to do with Amanda’s murder.
As part of the plea deal, she agreed to no longer work at the Department of Human Services in Newaygo County.
She was sentenced to 30 consecutive weekends in jail and, most importantly for Amanda’s family, ordered her take a polygraph test about the murder.
