Sheriff's investigators say their work to find those responsible for a shooting outside an events center near Austin that left five wounded has been hampered by uncooperative witnesses.
The five victims ranged in age from 17 to 23 years old. Two remain in critical condition.
Mower County Sheriff's Chief Deputy Mark May said Monday no arrests have been made in the shooting outside the former Lansing Corners supper club, located about 15 minutes north of Austin.
May says a "rap party" got out of control early Sunday and as security staff broke up the crowd, shots rang out in the parking lot. The chief deputy estimates there were about 200 people in the parking lot, but they claim they did not see anything.
Detectives say they have not yet ruled out the possibility that the shooting was gang-related.
May says two small-caliber handguns were used in the shooting, but he would not say whether they were recovered.
Officials say the two victims that were critically injured are from Rochester and Sioux Falls, S.D. Both were shot in the chest.
