Troy Davis, a 42-year-old man convicted of murdering a police officer in Savannah, Ga. was executed by lethal injection at 11:08 p.m. tonight.

In 1991, Davis was convicted of the 1989 murder of officer Mark MacPhail.

Davis escaped three executions before, but was denied clemency shortly before his execution.

On Friday, Sept. 15, students from Temple rallied at the Bell Tower against the execution.

Many prominent organizations and public figures have claimed Davis’ innocence throughout the past 20 years, rallying in his defense until the end.

Davis reportedly maintained his innocence tonight, telling MacPhail’s family members that were present at the execution that he did not commit the crime he was convicted of.
