The Michigan Court of Appeals today heard the case of a 14-year-old boy convicted of four murders.
The court is considering evidence that the now 20-year-old man may be innocent.
In 2007, four people were shot in a Detroit neighborhood.
Police picked up Davontae Sanford, a partially blind, developmentally-delayed 14-year-old.
They held him for questioning without a parent or attorney present.
Sanford confessed and was given decades in prison.
Then, a convicted hit man, Vincent Smothers, said he - not Sanford - committed those murders.
