Another witness said he saw Neff with the same gun earlier in the day, according to Hunt. There was also a key to a Dodge vehicle near the gun, said Hunt.
"I also learned that when the pickup was stolen, a Makarov 9mm was inside the vehicle," said Hunt.
Harper-Head said the gun was found in an area where Neff was sitting.
The other subjects in the apartment said Neff paced, and acted nervously and observed law enforcement movements from the window.
Stark said he saw Neff driving the stolen truck.
Neff denied having any involvement in either incident.
Neff was placed under arrest for assault and battery with a deadly weapon, felonious pointing of a firearm, possession of a known stolen vehicle, possession of a firearm while committing a felony and possession of stolen property.
