After an ongoing investigation that began in March, Kennewick police have arrested a 71-year-old man in connection with possession of an illegal firearm. What they found in his home was a lot MORE than one.

Joseph L. Hennessey was being looked over an alleged assault incident. Information obtained by Kennewick detectives indicated a likely illegal firearm possession.

Tuesday, officers raided a home at 304 South Jefferson, and arrested Hennessey, but multiple firearms were found in the home.  So far he's facing one count of illegal possession. Authorities did not specifically say if all the guns were his, the investigation continues.
