UPDATE (WKOW) -- Authorities conducted a controlled detonation Wednesday inside the Beaver Dam apartment where one man died in an explosion Monday.

Beaver Dam Police Chief  John Kreuziger said at a Wednesday morning news conference that the apartment contained, "highly volatile, homemade explosives."

"They are so sensitive and cannot be removed," Kreuziger said. 

As a result it took until Tuesday to remove the body.

The detonation took place at approximately 1:30 p.m. Wednesday.  Before the blast, nearby streets were closed, sandbags were place in the apartment complex, windows were boarded up and people evacuated.

At the time of the detonation, flames could be seen in the apartment building as a portion of the building slightly collapsed.

Authorities say damage from the detonation was primarily to the apartment and adjacent apartments, with some damage to the building's structure.

Police were called about 1 p.m. Monday, March 5, 2018, to the Village Glen Apartments on Knaup Drive for a report of an explosion. 

The blast it blew out the windows and a sliding glass door in a second floor apartment.

"I heard an explosion that rattled windows and obviously looked at the clock and I knew something didn't make sense. It was a pretty loud explosion," Kirby Krohn told WISN.

Kreuziger said that upon entering the unit, officers saw a large number of chemicals.

"We took photos and we forwarded them to the FBI. We got information back that definitely those are explosive devices," he said.

The person discovered dead in the apartment has not yet been identified, and the investigation could take weeks or months, Kreuziger said. 

On Tuesday, officials ruled out a meth lab as the cause of an explosion, and Kreuziger said investigators still don't know exactly what the chemicals are.

Chemicals also were found in a garage associated with the apartment, Kreuziger said.

FBI Special Agent Justin Tolomeo says evidence was preserved prior to the Wednesday detonation.

Tolomeo says the Monday explosion appeared accidental.  He made no reference to the suspect-victim losing his life in the process of trying to bomb something in the apartment complex.

Police are allowing the occupants of the following apartment complexes to return to their apartments: 115, 117, 119, 123, 125, 127 and 129 Knaup Drive, and 222, 224, 226 and 228 East Industrial Drive.

The Beaver Dam Police Department and Dodge County Sheriff’s Office is maintaining the evacuation order in place for all other residences that have already been evacuated, although they some of the still-evacuated residents will be allowed to move back in Wednesday evening or Thursday.

A law enforcement source says there are similarities to what was found in the Beaver Dam apartment, and explosives material found in a Madison apartment, but said there was no apparent connection between the suspects in the two cases.
