(AP) — A former North Texas justice of the peace and his wife have been indicted on capital murder charges in the slayings of three people, including two prosecutors.

A local grand jury indicted Eric and Kim Williams on Thursday.

The couple is accused of killing Kaufman County Assistant District Attorney Mark Hasse, District Attorney Mike McLelland and McLelland’s wife, Cynthia. Hasse was shot outside the county courthouse in January, while the McLellands were killed in their home in March.

Prosecutors allege Eric Williams was the gunman in both cases.

The two were arrested in April for what prosecutors allege was a meticulous plot to avenge Eric Williams’ conviction for stealing county computer monitors in 2012.

Eric Williams is being held on a $23 million bond. His wife’s bond is $10 million.
