Preliminary autopsy findings show that Alicia Hummel had blunt-force trauma to the head and incision wounds to the neck.
The homicide investigation is ongoing, and final autopsy results will be released when the final report has been completed, the South Dakota Attorney General's Office said in a news release.
The final report could be issued yet this week, said Sara Rabern, a spokeswoman from the attorney general's office.
Attorney General Marty Jackley and Clay County Sheriff Andy Howe renewed their request for the public's help providing any information about suspicious activity in the Myron Grove state recreation area near Vermillion on June 1.
Individuals with any information can call the Clay County Sheriff's Office at (605) 677-7100.
VERMILLION, S.D. | Preliminary autopsy results of a Sioux City woman found dead last week in a remote area of Clay County, S.D., are in, but authorities are waiting to receive the final report before making the findings public.
Clay County Sheriff Andy Howe said Tuesday that authorities preferred not to announce preliminary findings from Alicia Hummel's autopsy in case the final report offered information that differed from the initial findings. He said the final report from the Minnehaha County, S.D., medical examiner should be received this week, possibly Tuesday.
Hummel, 29, was found dead the afternoon of June 1 at a boat dock at Myron Grove, also known as the Highline Area. The remote area along the Missouri River is about seven miles west of Vermillion. Hummel was found in the water near the shore by a state boat ramp attendant. Her death is being investigated as a homicide.
Her funeral was Tuesday morning at the Church of the Nativity, 4242 Natalia Way.
Hummel had gone fishing at the boat dock, and was on vacation from her job at Siouxland Family Center in Dakota City, where she taught Early Head Start classes.
Howe said investigators have yet to find her cellphone, and several pieces of evidence taken from the scene are still being processed at the state crime lab.
"The leads are getting fewer and fewer, but we're following up on all of them," Howe said.
Authorities are still seeking a dark-colored sedan with tinted windows and a loud exhaust system that might be connected to the death. Howe said witnesses reported the vehicle was in the area at the time Hummel’s death reportedly occurred. Howe said investigators would like to speak with anyone who may have been driving in that area the day of Hummel's death.
"People are still focusing on that dark vehicle, but we'll talk to people who were in any vehicle that was in the area," he said.
Investigators have spoken to many of Hummel's friends, but Howe said anyone who might have spoken to Hummel about her plans for her fishing trip or spoke to her the day she died should contact the Clay County Sheriff's Office at (605) 677-7100.
