Input: Mario Casciaro  who was sent to prison for 26 years for the murder of his teenage co-worker  only to be freed after the conviction was reversed   is now seeking millions of dollars in damages from those who brought the case against  him .
It took two trials before  Casciaro  was convicted in 2013 of the unusual murder by intimidation charge in the presumed killing of 17-year-old Brian Carrick. In what had been â and now remains â one of McHenry County's most mysterious cases  Carrick disappeared in 2002 after being seen at the Johnsburg grocery store where he and Casciaro both worked. His body has never been found.
Authorities contended that Carrick was selling pot for  Casciaro  and owed him money.
A third co-worker  Shane Lamb  testified at both trials that  Casciaro  told him to "talk" to Carrick about the debt. Lamb said he confronted Carrick inside a produce cooler at the grocery store and punched him  knocking him unconscious. Lamb testified that  Casciaro  told him to leave the store and that he would take care of the body. Authorities said Carrick's blood was found in and around the cooler  but  Casciaro  has denied having any involvement.
Lamb  facing a lengthy sentence in an unrelated drug case  agreed to testify against  Casciaro  in exchange for immunity in Carrick's death.
 Casciaro   now 33  was released from prison in 2015 after an appellate court ruled that the state's case was improbable and Lamb's testimony did not match the physical evidence found at the scene.
