Bomb-making supplies seized from West Allis business; Milwaukee man charged
A Milwaukee man is charged with possessing materials to make improvised explosive devices after police seized bomb-making components from his workplace following an anonymous tip.
Anonymous tip sparks investigation
The backstory:
The accused is 48-year-old Joseph Godlewski. He was charged with possession of an improvised explosive device.
According to a criminal complaint, West Allis police received an anonymous tip alleging Godlewski was making pipe bombs at his workplace, Metropolitan Maintenance and Landscaping, on Dec. 30, 2025, and had previously assembled and detonated an explosive device.
The tipster also claimed Godlewski ordered bomb-making components online, including materials from Amazon.
Investigators searched the business and located an office labeled with Godlewski’s name that contained multiple bags of chemical powders, including sulfur powder, potassium nitrate and aluminum powder, as well as cylinder tubes, fuses, glue sticks and a digital scale with powder residue, per the complaint.
Bomb squad called, business shut down
Dig deeper:
The Milwaukee Police Department Hazardous Device Unit was called to the scene to seize the materials. Authorities shut down the business for about six hours, so the items could be safely removed, according to court records.
A Milwaukee police bomb squad sergeant told investigators the materials were both "emergent" and "inert" components used to construct improvised explosive devices and that all necessary items were present to assemble multiple devices capable of causing bodily harm or property damage if properly assembled.
