According to court documents, 45-year old Miguel Moran Diaz was arrested outside his Miami apartment earlier this month.

Court documents said Diaz  described himself as a “lone wolf” for the terrorist group known as ISIS and wanted to act as a sniper, killing people in Miami.

A criminal complaint filed in federal court revealed Diaz met with an undercover FBI source who claimed he could sell Diaz guns and ammunition.

In one conversation, the documents says “Diaz stated that after killing people, authorities would find the ISIS engraved shell casings and then know there was a sniper in town.”

The affidavit reveals he also discussed the Boston Marathon bombings and showed the source detailed instructions on how to build bombs.

When the source asked about his girlfriend who lived with him at the apartment on Northwest 14th Street, the complaint says “Diaz also stated that he threatened to kill her if she called 911.”

“I heard a big noise and came out here, they was all around here, quite a few of them, heavily armed,” neighbor L.C. Harris recalls about the day Diaz was arrested.

The affidavit says FBI agents found multiple weapons in Diaz’s car and apartment.

Neighbor Lucilo Gonzalez says Diaz was always polite, greeting him each time they crossed paths.

“He see me and talk to me with respect all,” Gonzalez said. “I don’t know what happened with him.”

Diaz was arrested and charged with possession of a firearm by a convicted felon.

Neighbors said it’s the reference to ISIS that has them more concerned.

“It’s a little bit scary to see something like that, so I’m glad they was on to him,” Harris said.

Diaz spent 46 months in prison on cocaine possession and conspiracy charges.

Diaz is originally from Cuba and he faces deportation whenever he is released from custody.
