A Rolla man convicted of killing two people and injuring another at a Miller County RV park will be sentenced this week. Gary Sweet entered guilty pleas to two counts of second-degree murder, one charge of first-degree assault, and one charge of second-degree assault. He shot and killed Jim and Sheri Parker in November of 2017 a couple weeks after they had kicked him out of the River View RV Park and Campground. He then opened fire into a camper, injuring one person who was inside at the time. Sweet will be sentenced Wednesday.
