A 41-year-old California man was sentenced to 24 years in state prison on Monday after pleading no contest to voluntary manslaughter and admitting to a separate felony sexual battery charge in connection with the 2023 death of Amery Sweany in Marysville, California.
The sentencing, handed down by Yuba County Judge Julia Scrogin, concludes a multi-year investigation into the death of Sweany, whose body was discovered following an incident that prosecutors say involved stalking, theft, and a vehicular assault in an orchard.
Incident Overview
According to the Yuba County District Attorney's Office, the sequence of events began on April 26, 2023, after Sweany parted ways with a witness in Yuba City and traveled to a parking area near a Habit Burger and an ampm convenience store in Marysville. Surveillance footage showed Ricky Singh Lasher repeatedly circling Sweany, approaching her, and eventually taking her bag, which contained all of her belongings, and driving away.
Sweany remained in the area for roughly 50 minutes before walking down an alley and east on 8th Street, where surveillance cameras captured Lasher's truck traveling in the opposite direction. Investigators said Lasher later persuaded Sweany to enter his rented truck by offering her drugs, drove her to an orchard, and attempted to sexually assault her. Prosecutors stated that Sweany fought back and fled on foot, at which point Lasher followed her in his vehicle, veered off the road, and ran her over between rows of trees before leaving the scene.
