Reports have surfaced that at the time Jonathan Martin was detained for his threatening Instagram post, he had the weapon that appear in the post in his car.  It looks like he may have been getting ready to act on those threats.

Via TMZ Sports:

A disturbing new twist in the Jonathan Martin saga … law enforcement sources tell TMZ Sports the ex-NFL lineman had a gun in his possession when he was detained by police.

As we previously reported … cops tracked down the former Miami Dolphins player Friday after he posted a photo on IG showing a shotgun and ammo — along with a threatening message and the names of former teammates and high school acquaintances.

We’re told cops believe Martin had recently purchased two weapons — one of which matched up with the gun in the IG post. Sources tell us when they found him on Friday, he had a gun in his car that fit the description police had.

Good thing they got to him before he carried anything out.  Hopefully Martin is getting the help he needs.
