SEMINOLE COUNTY, Fla. -- When Shoot Straight gun range opens its doors Tuesday morning it will not rent any guns to customers.

The Casselberry gun range became a crime scene for the second time in a month, after 26-year-old Jason McCarthy of Winter Springs rented a gun and killed himself inside the range Monday.

The owner's attorney told Eyewitness News they are asking the state to allow them to do background checks on customers before they rent guns. Until then, they will sacrifice the money normally made on rentals.

Twice in one month, Casselberry police had to swarm the Shoot Straight gun range because someone was killed inside. This time a man from Winter Springs shot himself in the head and died.

"This is crazy, you know," said Andrew Colon, Casselberry resident.

Three weeks ago, Marie Moore shot and killed her son Mitchel in the same gun range and then killed herself. Family members told police she had a history of mental illness.

McCarthy's family said he had mental problems, too.

"There needs to be something done, people committing suicides and murders and all that. It's getting out of control," said Colon.

The shooters in both cases rented guns from the facility. The attorney for Shoot Straight, Joerg Jaeger, says that will no longer be allowed at any of its Florida locations.

Jaeger believes the problem is that the state does not allow background checks unless customers buy a gun. As a result, the store can only rely on people who rent guns to tell the truth when they sign a form that asks about felony convictions, your mental state and whether you take medication.

"We just think it's a safety issue. We don't know any other way to do it. We've tried everything else we can," said Joerg Jaeger.

McCarthy's family did not want to talk, but said they knew he had a history of mental illness. However, they did not believe he would take his own life.

Casselberry police expect to take a look at the surveillance video from inside the gun range sometime Tuesday morning. They want to see if there is anything that may have led to McCarthy shooting himself.

Shoot Straight is already facing a wrongful death lawsuit, as a result of the previous shooting when Marie Moore shot and killed her son Mitchel before turning the gun on herself.

Mitchel Moore's father filed the suit, claiming the business should not have rented her a gun.
