Authorities in Beaver Dam still haven't identified the man killed in an apartment explosion Monday afternoon.
Following the blast earlier this week at 109 Knaup Dr., investigators also found homemade explosives inside of the apartment.
At 1:31 p.m. Wednesday, authorities secured the unit and conducted a controlled detonation to blow up what the police chief described as the volatile chemicals inside.
Sand bags were strategically placed around the apartment to absorb the explosion, according to Beaver Dam Police Chief John Kreuziger.
The chief added nearby doors and windows were also boarded up.
The building housing the apartment still sustained some structural damage.
"We knew there would be some damage to the unit itself, and to some of the surrounding, adjacent apartments," said Justin Tolomeo, Special Agent in Charge of the FBI's Milwaukee Division. "That did occur."
Firefighters were called in following the blast to extinguish a blaze impacting the attic and adjacent apartments.
"The operation was a success and eliminated the threatening, explosive material," Kreuziger said.
