Police now have four suspects in custody, and two of those men have been charged with murder, Sgt. Loren McManus of the Sioux Falls Police Department said.
Brian David Anderson, 20, and Trevor James Kruthoff, 17, both of Watertown, were taken into custody by Division of Criminal Investigation Agents in Watertown Tuesday.
McManus said Anderson and Krutfhoff were both in the home on N. Alaska Drive when 20-year-old Jordan Duane LeBeau was fatally shot Monday. LeBeau's father, 48, remains hospitalized from injuries sustained in the incident.
Anderson and Kruthoff face 1st Degree Robbery, 1st Degree Burglary, Aggravated Assault, 1st Degree Murder and Attempted 1st Degree Murder charges.
Kevin James Rice, 20, and Douglas Peter Scholten, 20, both of Dell Rapids, were also arrested Tuesday under charges of 1st Degree Burglary, 1st Degree Robbery and Aggravated Assault.
Public Information Officer Sam Clemens said Rice and Scholten were not in the home during the shooting, but they were involved.
Rice was arrested at an auto body shop north of Dell Rapids around 8:30 a.m., Minnehaha County Sheriffs said. He gave up without incident.
Around 9:30 a.m., police believed Scholten was in a home at 606 E. 9th St. in Dell Rapids.
Because of the proximity of this home to local schools, authorities secured the perimeter of the schools, keeping students in buildings until the suspect had been found. Some students were moved from the north side of St. Mary Catholic School because the school is directly across the street from the home on 9th St.
In the process of gathering intelligence, police learned Scholten was not home, but working on a farm east of Dell Rapids at 24607 481st Ave. It was confirmed that he was at the hog confinement, and he was arrested without incident.
The investigation is ongoing McManus said.
