In a press release, issued by the Nebraska Attorney General’s office Wednesday, April 24, Anthony A. Mattison, a 35 year-old-man from Osceola has been charged in Clay County Court for the murder of Jasmine Garnett, which occurred in September of 2022 outside Harvard. Garnett was found deceased Oct. 5, 2022. Mattison is charged with one count of first-degree murder, a Class I or IA felony; one count of use of a firearm to commit a felony, a Class IC felony; one count of possession of a firearm by a prohibited person, a Class ID felony; and one count of improper disposal of human skeletal remains, a Class IV felony.
The Nebraska State Patrol is the lead law enforcement investigative agency in this matter.
The case will be prosecuted by the Clay County Attorney’s Office with the assistance of the Nebraska Attorney General’s Office.
According to reports, Mattison was the last person to see Garnett alive about a month prior to her remains being found in the Harvard area, by a person working in the area on Road 26, near Harvard’s sewer lagoons. At the time the remains were located, the body of a woman was presumed to be 25-year-old Garnett, who had been missing since Sept. 16.
Mattison also faces charges out of Hall and Platte counties, and he’s charged with attempted murder, attempted assault, terroristic threats and two weapons charges in connection with a shoot-out with Hastings police, where he was accused of firing a gun at Hastings police officers, which happened approximately 10 days after Garnett was reported missing. Mattison was ruled to be incompetent to stand trial on the Hastings charges. He was treated at the Lincoln Regional Center, and last month, after reviewing reports from the Regional Center, a judge ruled that Mattison is now fit for trial in the case. Mattison’s first court appearance in Clay County Court is scheduled for May 14, 2024, at 10 a.m.
