Smith said he was unaware that the water in Thomas' cell had been turned off.
"The only legitimate reason is if the cell is flooded or he's doing things to make the cell flooded," said Smith.
A lieutenant with the Milwaukee County Sheriff's Office, who was also on shift the night Thomas died, said that Thomas had been moved from a mental health unit at the jail where he had flooded his cell.
But it's not policy to preemptively turn off the water in a new cell based on past behavior.
Court testimony also revealed that jail policy has changed following Thomas' death. At the time, it was up to an officer's discretion to turn off the water to an inmate's cell. Now, only a lieutenant has that authority.
There are potentially 90 witnesses who could testify in this inquest. A county judge said it could take the entire week.
