INDIANAPOLIS (AP) — A man charged with murder for his role in a deadly Indianapolis house explosion has reached a plea deal weeks before his scheduled trial.

Marion County Prosecutor Terry Curry said Tuesday that Gary Thompson has agreed to plead guilty to conspiracy to commit arson resulting in serious bodily injury. His plea agreement calls for a 30-year prison sentence, with 10 years suspended.

The 45-year-old Thompson had faced a September trial on two counts of murder and other charges in the November 2012 house explosion that killed two next-door neighbors.

Prosecutors say Thompson was one of five people involved in a plot to destroy the home with natural gas to claim insurance money.

Two others have been convicted, a third reached a plea deal and another faces a November trial.
