UPDATE: At around 6 p.m., Sioux Falls Fire Rescue held a media briefing saying they recovered the body of a man who had been trapped under the collapsed Copper Lounge in downtown Sioux Falls.

ORIGINAL STORY: One person has been rescued from a collapsed building in downtown Sioux Falls, while crews work to rescue another man still trapped inside.

The 22-year-old woman was rescued around 1:30 p.m. The woman, identified as 22-year-old Emily Fodness, lived in an apartment in the building. Authorities say she had minor injuries to her leg, but is expected to be okay.

A dog was rescued from the building minutes before. Authorities say the dog belonged to Fodness, and they had been near each other since the building collapsed at 10:30 a.m.

Fodness was wearing only a t-shirt and shorts. Temperatures throughout the day hovered around 32 degrees.

Sioux Falls Fire Rescue Chief Jim Sideras tweeted a photo of the woman being rescued, stating she said "hi" to her parents before she was taken to the hospital.

A construction worker is still trapped inside. Crews are working to rescue him.

Lt. Loren McManus of the Sioux Falls Police Department says he is hopeful crews will find him. He said authorities have a general idea of where he is, though they are still unsure of his exact location.

A K9 unit from Rapid City is being flown in to assist in recovery efforts. Additional search and rescue crews from Rapid City and Aberdeen are also on their way to provide support.

According to Sioux Falls Fire Rescue, Skelly's, a pub located right next to the building, also received damage in the collapse. Authorities believe the foundation of the building is now compromised.

Authorities are asking the public to avoid the area around 10th Street and Phillips Avenue, where the building collapsed, as crews continue in their recovery efforts.

The building most recently served as the Copper Lounge, which recently closed. It was expected to reopen in the spring as a drug store

The cause of the collapse is still under investigation.

ORIGINAL STORY:

The old Copper Lounge building in downtown Sioux Falls has collapsed, trapping two people inside.

A construction worker and an occupant of the building are trapped inside.

The building collapsed around 10:30 a.m. Friday. The area has been closed to traffic. Police say people should avoid the area of 10th and Phillips.

Crews are working to stabilize the building, and are trying to get the people out. Medics are on the scene to help with the rescue.

Several witnesses at the scene tell KSFY News that one of the people trapped inside is a 22-year-old woman. They say the area of the building that collapsed was her apartment bedroom.

Sioux Falls Fire Rescue Chief Jim Sideras says firefighters have been in contact with her. They have not been able to make visual contact with her at this point.

Sideras says the second person trapped inside is a construction worker. He believes crews have heard him making pounding noises from within the rubble, though they are unsure exactly where he is at.

Crews are moving "slowly and methodically," Sideras says, to avoid causing further collapses.

There were other construction workers in the building at the time of the collapse, but they were able to make it out safely.

Crews rescued a dog from the rubble around 1:10 p.m.

The building has been vacant since September and was expected to reopen in the spring as a drug store.

It is still unclear what caused the building to collapse.
