Seth Horvitz, 38, a musician from San Francisco who moved to Washington a year ago, told The Washington Post he was alone getting ready for a dinner party at his Brookland apartment when he heard a knock at the door. A UPS man had left a package outside.
He had ordered the TV set for $324 from a third-party seller through Amazon. He told the Post he thought the package might be TV accessories.
But Horvitz got a surprise when he opened the package and found a "tactical military-style SIG716 semiautomatic rifle ... with an empty magazine for 7.62x51mm ammunition" and an owner's manual from German arms company Sig Sauer, the Post said.
Horvitz, who said he's never handled a weapon before, said an invoice with the gun showed it was meant to be sent to a Pennsylvania gun shop. Horvitz and his guests had their dinner party, looking at and discussing the assault rifle.
The Post said he called police, who came by a week later and drove off with the weapon.
"I definitely knew it was a mistake," Horvitz told the Post. "But I was confused as to how that kind of mixup could happen. Especially given the recent events, the recent shootings. It surprised me to see how easy it would be for a gun to show up on someone's doorstep -- not just a gun, but an assault weapon."
The Post said Amazon did not respond to calls for comment. Horvitz said he still wants his TV.
