Police and ATF raid East Windsor gun shop after theft of AR-15 from store.

Oh, and it’s the same store that had sold the gun used in the Sandy Hook massacre.

Adam Lanza had two pistols and the AR-15 when he entered Sandy Hook Elementary School Friday morning, and in just a matter of minutes, he fired multiple rounds, killing 20 children and six adults. Before the school shooting, he shot his mother four times.

Riverview Gun Sales is the same store where police believe a different man stole an assault weapon and was trying to carry out a similar attack.

In a video obtained by Eyewitness News, Jordan Marsh, 26, of South Windsor, can be seen stealing an AR-15 with a scope just four days earlier.

Marsh was caught stealing a 50-caliber long gun from the Riverview Gun Sales on Saturday. Police found the AR-15 in a duffel bag in a room at the Hartford Hilton that day.

“It’s scary, I mean I got three kids,” said Sharon Hodge of South Windsor, who spoke with Eyewitness News.

For the past two years, she has opened her home to Marsh, who is her boyfriend’s son.

Marsh, who Hodge said suffers from schizophrenia as well as other mental issues, was off his medication when he was arrested Saturday.

“It’s unbelievable,” Hodge said after seeing the story on WFSB.

Police said Riverview Gun Sales had no idea the AR-15 Marsh stole was missing. Management at the store didn’t know about 11 guns that Marsh had allegedly stolen last year until they were notified by detectives.

Inventory control issues at Riverview Gun Sales have occurred before. In 2007, state police raided a Somers home and found a bunch of stolen guns from the store.

“It was found that the same Riverview gun store was missing upwards of 30-plus guns,” said East Windsor police Detective Matthew Carl.

If gun shops have such lackluster security, do we expect anyone else to do better?

Apparently this gun shop has no clue about its inventory - they only learned of the stolen guns after police told them of the thefts.

Here’s what I don’t get - video purportedly shows the thefts, but the store didn’t know they had occurred? Was this BATF or local LEOs who had their own cameras installed, or was this further incompetency by the store to not actually view/review security video.
