Federal agents arrest Cincinnati man in case alleging links to 3 shootings

Federal agents arrested a 27-year-old Cincinnati man on September 11 after prosecutors alleged that firearms recovered from him were connected to a February homicide and two later shootings.

Lamont Champion faces a federal charge of possessing a firearm after a felony conviction. He appeared in federal court for an initial appearance that afternoon, according to the U.S. Attorney’s Office for the Southern District of Ohio.

The arrest is not a finding of guilt. The alleged connections to the shootings come from a criminal complaint, and the government must prove the firearm charge in court.

What prosecutors allege

According to the complaint, law enforcement recovered a firearm from Champion in June 2026. Prosecutors said ballistic results from that firearm matched cartridge casings recovered after a February homicide involving two victims at the Villages of Roll Hill in Cincinnati.

Agents later executed a search warrant at Champion’s residence on September 11. The U.S. Attorney’s Office said they recovered the 9mm handgun allegedly used in two later shootings, along with a second firearm.

Prosecutors allege that the 9mm handgun was used in a July shooting on East Clifton Avenue and in an August shooting involving occupants of a car near the Enclave Event Center. The announcement said NIBIN analysis indicated that the same firearm was used in both incidents.

Those allegations do not establish that Champion committed the homicide or either shooting. The federal announcement also did not establish the identities of the victims or the final investigative status of those cases.

How NIBIN fits into the case

The alleged links involve the National Integrated Ballistic Information Network, or NIBIN. The Bureau of Alcohol, Tobacco, Firearms and Explosives says the system digitally images markings left on fired cartridge casings and compares them with images from other crime scenes and recovered firearms.

ATF says NIBIN can help investigators identify possible links between shootings, including across cities or states, and produce results faster than traditional manual comparisons. It is an investigative system that generates leads; it is not a firearm registry, and a NIBIN result alone is not a substitute for proving a criminal charge.

A separate September 11 shooting

Cincinnati police also investigated a separate shooting near the University of Cincinnati in the Short Vine area on September 11. WCPO reported that a man was shot in the stomach near campus and taken to a hospital with non-life-threatening injuries.

That incident should not be conflated with the federal allegations against Champion. The materials announcing his arrest do not say that he was involved in the Short Vine shooting.

What happens next

Prosecutors said Champion has prior felony convictions involving fentanyl and firearms. Possessing a firearm as a previously convicted felon carries a statutory maximum of 15 years in prison if a defendant is convicted. That is a legal maximum, not a prediction of the sentence.

Future developments could include detention proceedings, an indictment, additional court filings or further disclosures about the alleged evidence. Champion is presumed innocent unless and until proven guilty.
