Leonetti was in a relationship with Jacob Jedidiah Thayer. The couple had a 4-year-old daughter. 
On Thursday April 12, 2018, Leonetti was allegedly shot and killed by Jacob Thayer at their home. Deputies arrived at the home on Hilltop Street in Pine Grove at around 3:00 a.m. after getting a call from a woman saying her son had killed himself. Outside of the home, deputies found the 60-year-old woman and Leonetti's daughter. 
Investigators believe Jacob Thayer shot Richard Thayer and Leonetti multiple times before turning the gun on himself. A partially loaded Glock .40 caliber pistol was found next to Jacob Thayer’s body.
