HOUSTON (AP) — Prosecutors say they will retry a former deputy's husband charged in the death of a man he and his wife confronted outside a Houston-area restaurant.

The Harris County District Attorney's Office said Monday it's still determining when a retrial will be held.

A mistrial was declared on Saturday in the murder trial of Terry Thompson after jurors deliberated more than 26 hours over three days.

Thompson and his wife, Chauna, were each charged with murder in the May 2017 death of 24-year-old John Hernandez.

Chauna Thompson was a Harris County sheriff's deputy at the time but was later fired. Her trial is scheduled for October.

A group of local activists planned to hold a protest over the mistrial on Monday afternoon in downtown Houston.
