Continued Need for Public's Help in New Berlin Explosion Case

NEW BERLIN, Wis. — The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), in conjunction with the New Berlin Police Department, continue to urge the public to report information related to the New Berlin, Wisconsin, explosions that occurred earlier last week.

Investigators are looking specifically for information related to individuals who may have been operating a vehicle Monday, Sept. 17, around 4:00 p.m. in the 18300 block of W. Coffee Road. The vehicle reportedly witnessed the explosion, stopped, took photos of the scene and then drove away.

ATF believes information related to this reported scenario is critical to the investigation and continues to offer a reward of up to $5,000 for information that leads to the arrest and conviction of the person(s) responsible for the recent explosions.

Those with information can dial 1-888-ATF-BOMB, email or submit an anonymous tip through the ReportIt app which is available on Google Play and the Apple App Store, or by visiting When reporting, be sure to include as many details as possible and contact information for potential follow up if a reward is sought.

Evidence recovered during this investigation supports two explosive device detonations. The first occurred Saturday, Sept. 15, in the early morning hours, and the second occurred Monday, Sept. 17. There were no reported injuries related to either detonation.

ATF protects the public from crimes involving firearms, explosives, arson, and the diversion of alcohol and tobacco products; regulates lawful commerce in firearms and explosives; and provides worldwide support to law enforcement, public safety, and industry partners.
