Investigation Discovery to Present World Premiere Docu-Series Killing Richard Glossip, 3/5

For almost twenty years, two men convicted of murder one on death row, and the other sentenced to life without parole maintain two very different accounts of what led to the slaying of Barry Van Treese on January 7, 1997, at the Best Budget Inn in Oklahoma City. Richard Glossip, a man with no prior felony convictions, has consistently maintained his innocence, insisting that he had no knowledge that anyone planned to kill Van Treese.
