More details have been released in a possible double murder suicide in Pine Grove. 

According to authorities, on Thursday April 12, at approximately 3:05 a.m. the Amador County Sheriff’s Office received a 911 call from a female subject reporting that her son had killed himself at her residence on Hilltop Street in Pine Grove.

Sheriff’s Deputies responded and were on scene within two minutes. Upon arrival, deputies contacted the 60-year-old female along with her 4-year-old granddaughter who were waiting outside. Upon entry into the residence, deputies located 26-year-old Jacob Jedidiah Thayer, 27-year-old Marie Ann Leonetti, and 60-year-old Richard Roger Thayer II. All three were deceased and all had suffered gunshot wounds.

The preliminary investigation revealed that Jacob’s mother had left the residence earlier that evening to care for a family member. Just before 3 a.m. she received a call from her 4-year-old granddaughter on Richard’s cellular telephone stating that her father had shot himself. The woman then drove to the residence where she found her granddaughter and the three decedents.

Richard and Marie both appeared to have suffered multiple gunshot wounds. Jacob had one apparent gunshot wound, consistent with it being self-inflicted. A partially loaded Glock .40 caliber pistol registered to Jacob was found at the scene next to him.

The investigation into this tragedy is active and ongoing.
