An Effingham County man fatally shot himself Wednesday afternoon after authorities arrived at his house with a warrant for his arrest.

Martin Geyer, 54, of Rincon died from a self-inflicted gunshot to the head following a standoff with Effingham County Sheriff’s Office deputies and U.S. marshals, according to ECSO spokesman Detective David Ehsanipoor.

Geyer was wanted for a bond violation related to charges out of Columbus, Ohio, for mail fraud, possession of anabolic steroids and unlawful possession of a gun.

“He had made comments to some other people that he was not going back to prison and that he had a firearm,” Ehsanipoor said. “We knew we were probably dealing with somebody who felt like he had nothing to lose, which obviously posed a threat to not just us but anyone else around him.”

Deputies and marshals arrived at Geyer’s 117 Cobbleton Drive home around 3 p.m. Geyer refused their requests to walk outside.

With the house surrounded, deputies heard a single gunshot from inside.

“Just because you hear a gunshot, you don’t know whether he killed himself or whether he’s shooting at somebody,” Ehsanipoor said.

Deputies entered the house and found Geyer in an upstairs room. He had a head wound and was pronounced dead at the scene.

An autopsy Thursday at the GBI Crime Lab in Savannah confirmed Geyer died from a single, self-inflicted gunshot to the head.

Geyer was facing three years in federal prison on his charges, according to investigators.

“He said he wasn’t going back to prison and obviously he meant it,” Ehsanipoor said.
