SIOUX CITY | Two days after Alicia Hummel's body was found at a boat dock in rural South Dakota, many who knew her gathered Wednesday night for a vigil in her memory.
More than 50 people held lighted candles and silently formed a circle on a field at Sioux City East High School, where Hummel once practiced with the school's marching band.
Hummel loved fishing and country music, said her friend Dejay Langel, of Jefferson, S.D. Langel played a song by one of Hummel's favorite artists, Luke Bryan, through a sound system set up on a hill above the field.
"When I got the news today/I didn't know what to say," the song began.
Hummel was found dead Monday in a state recreational area in rural Clay County, S.D. State and local authorities continued to follow up on leads Wednesday in their search for information about how the 29-year-old Sioux City woman died.
Clay County Sheriff Andy Howe said authorities have not yet received the autopsy report that they hope will determine the cause of her death.
Hummel's death is being investigated as a homicide.
"There are several people we'd like to talk to, but there isn't anybody I'd name as a suspect at this time," Howe said Wednesday.
Howe declined to comment on the physical condition of Hummel's body when it was found Monday 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 about 2 p.m. by a state boat ramp attendant.
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.
"We're getting a lot of tips about the reported dark car," Howe said.
Howe said the people in that car are not necessarily suspects, but investigators would like to ask them if they saw anything suspicious.
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.
A friend said Tuesday she thought Hummel had gone by herself, but investigators have not determined whether Hummel had company on her fishing trip.
Investigators collected several pieces of evidence at the crime scene, Howe said, but he declined to say what items were collected. Investigators continue to search for Hummel's missing cellphone, he said.
Howe said several of Hummel's friends have been interviewed, and investigators would still like to talk to anyone who might have spoken with Hummel about her plans on Monday.
