Bristol County man charged after 23 firearms, over 10,000 rounds of ammunition seized still incompetent to stand trial

A Bristol County man is still not mentally ready to stand trial after a hearing Wednesday in Fall River Superior Court.

According to police, in April of 2024, Mansfield Officers executed an arrest warrant for an individual with two default warrants out of Attleboro District Court for crimes committed in Mansfield and Norton. Probable cause was subsequently developed that there were a number of illegal firearms located at a residence on Church Street. Mansfield Police Detectives applied for and were granted a search warrant, and as a result, recovered 23 firearms, over 10,000 rounds of ammunition, high-capacity feeding devices, and items used for making improvised explosives.

After consultation with the Bristol County District Attorney’s Office, ATF, and the State Police Bomb Squad, Detectives applied for and were granted a second search warrant for the grounds of the property on Church Street. After speaking with neighbors and containing the scene, a thorough search of the grounds of the property was conducted with help from State and Federal partners.

As a result of the investigation, a 61-year-old Mansfield man was held on the default warrants and faces charges including Possession of a large-capacity firearm, Possession of a large-capacity feeding device, and Possession of a firearm without an FID card.

According to The Sun Chronicle, the suspect’s name is Thomas Callan.

According to court records, Callan has had multiple hearings on competency since his arrest. In Fall River Superior Court on Wednesday, the doctor and the Court found that he is still not competent to stand trial and recommends he be rescreened in three months.

A new hearing has been scheduled for February 4th.
