Police are hoping the public can help with their investigation into the shooting death of a Sioux Falls man. They say they are still trying to piece together how a 19-year-old was shot and killed over the weekend.

It was just before 4:30 a.m. Sunday when police say they found Dylan Widmann unconscious. They say a vehicle was parked in the middle of the road on North 1st Avenue, near the South Dakota State Penitentiary.

Officer Sam Clemens said, "The vehicle was running at the time and he had a gunshot wound to his right shoulder."

Police say Widmann was bleeding and he wasn't breathing. First responders tried to save him but were unsuccessful.

"He ended up dying from those injuries," said Clemens.

Officers found a gun and a shell casing, but police couldn't say where or whether Widmann was shot inside the vehicle.

Clemens said, "Detectives will go and talk to neighbors, anybody that may be around, try to find witness but I don't know specifically if they heard anything."

When asked whether Widmann's death could have been a suicide, police said they don't know yet.

"We're really not exactly sure what took place," Clemens said. "We don't believe there is any danger to the public, but as all investigations that could change once we learn more information."

Police say they are looking to talk to a few people, but as of right now no one has been arrested or charged for Widmann's death.

Police are asking anyone with information to report it to Crimestoppers at 367-7007.
