VERMILLION, S.D. | With preliminary autopsy findings in, South Dakota officials on Tuesday renewed calls for the public's help in finding a 29-year-old Sioux City woman's killer.
Preliminary results from the Minnehaha County, S.D., medical examiner show Alicia Hummel suffered blunt-force trauma to the head and incision wounds to the neck. Authorities are investigating her death as a homicide and are looking for information about suspicious activity in the Myron Grove state recreation area near Vermillion on June 1.
A state boat ramp attendant found Hummel's body in the Missouri River near the shore at the remote park, also known as the Highline Area. She 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.
Her funeral was Tuesday morning at the Church of the Nativity in Sioux City.
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 for the office.
Clay County Sheriff Andy Howe said investigators have yet to find Hummel's 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 is believed to have died. Howe said investigators would like to speak with anyone who may have been driving in that area the day she died.
"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 call the Clay County Sheriff's Office at 605-677-7100.
