BROCKTON — An investigation is underway after a Massachusetts State Trooper fired his weapon, injuring a Fall River man.

Massachusetts State Police say the incident occurred on Saturday at about 9 a.m. near a residential complex on Colonel Bell Drive in Brockton during a confrontation between the State Trooper and the suspect.

Police say during the confrontation, the suspect drew a firearm and pointed it at the State Trooper. The Trooper responded by firing his service weapon at the suspect, striking him in the lower body.

The suspect, Claude W. Brown-Madison, 25, of Fall River and formerly of Brockton, was transported to Boston Medical Center with a non-life threatening gunshot wound to his lower body. He is currently under Massachusetts State Police guard.

A firearm believed to be Brown-Madison's was recovered at the scene.

The reason for the initial interaction between the Trooper and Brown-Madison is under investigation.

Brown-Madison has been charged with armed assault with intent to murder, assault by means of a dangerous weapon, committing a firearm violation while having a record that includes at least three prior violent or drug crimes, unlawful possession of a firearm, and possession of a firearm and/or ammunition without an FID card.

The Trooper was evaluated at Good Samaritan Hospital and released. He has been placed on five days of standard administrative leave in accordance with State Police policy.

The incident is under investigation by multiple agencies. The Plymouth County District Attorney's Office has referred dual parts of the case to two other district attorney's offices because of a potential appearance of a conflict of interest.

The Cape and Islands District Attorney's Office will oversee the investigation into the shooting and will determine whether the use of potentially lethal force was justified.

The Essex County District Attorney's Office will prosecute Brown-Madison on the charges filed against him in connection to the incident.
