An 18-year-old Sioux Falls man was arrested after an overnight shooting left a teenager dead in southwestern Sioux Falls.

Dylan Michael Holler, 18, is charged with first-degree murder, first-degree robbery and aggravated assault after police say he shot and killed a 17-year-old boy at 11:03 p.m. Monday night at Bakker Park at W. 61st Street and W. Bakker Park. More charges are likely for Holler and others involved, Capt. Blaine Larsen with the Sioux Falls Police Department said.

Holler, the victim and two others were travelling together in a truck when an argument started over a drug-related activity, Larsen said. The two others in the truck were 18- and 16-year-old males. The name of the victim hasn't been released.

At some point, the group got out of the truck and began to fight, and Holler shot the victim once in the chest with a semi-automatic handgun, Larsen said.

Police were then called by witnesses who heard one gunshot. The victim was pronounced dead less than an hour later.

Holler had assaulted another person in the car, and that person was looked at by medical staff, but is out of the hospital with non-serious injuries, Larsen said.

Larsen said Holler left the scene in the truck and returned after a short time, which is when he was arrested. Police have yet to find the gun, and Larsen said it was likely stolen.

"Either the gun was transported by someone else, or it was ditched in the area somewhere," Larsen said. "We have had several searches, so there is a good likelihood someone took it out of that area."

Larsen is asking residents in the area to be on the lookout for it, and if they think they spot it, not to touch it, but call 911.

The homicide happened in the same area as a house party, and Larsen said the group had just picked someone up from the party when the shooting occurred.

Holler is known to police, but Larsen wouldn't get specific on what his criminal background entails. Court records show he has a few traffic violations and a recent charge of possessing drug paraphernalia.

His initial court appearance will likely be Wednesday in Lincoln County.

The homicide is the fourth this year to involve drugs, Larsen said. It is the seventh homicide in Sioux Falls in 2017, matching 2016's total.

"It's going to be a small quantity of drugs we re are talking about with a small amount of value," Larsen said. "It's a crime of opportunity. A lot of times people who are doing these drug rips, they figure the people they are stealing from aren't going to report it either."

Bakker Park is west of Interstate 29 and south of West 57th Street.
