MILWAUKEE (WTAQ) - An inquest will begin February 11th into the death of a Milwaukee robbery suspect while in police custody.

Circuit Judge Kevin Martens said Wednesday that the inquest will last for about a week.

The proceeding is designed to obtain testimony and evidence that could prosecutors decide whether charges should be brought against two officers in the death of Derek Williams.

A video released in September showed that the 22-year-old Williams was gasping for air and pleading for help for almost 8 minutes, while officers ignored him.

Police and prosecutors initially agreed that the officers did nothing wrong – but that stance is being re-examined in the wake of the video’s release.
