The Orlando gunman considered making one of the biggest tourist sites in the world the site of his deadly massacre - Walt Disney World.

Omar Mateen and his wife Noor Zahi Salman visited the theme park in April claims a federal law enforcement source who said that Mateen was looking at Downtown Disney and the gay club Pulse.

There have been no charges filed against Salman and it is not clear if they took their 3-year-old son with them when they went to scope out the park.

The law enforcement source who shared the news of a potential Disney attack with People learned the information after it was revealed to authorities by Salman while she was being questioned on Sunday.

Downtown Disney is billed as a 'eclectic mix of unique boutiques, one-of-a-kind eateries and jaw-dropping entertainment that will have you wondering where the day went.'

There is also no bag check or metal detector to get in, something Mateen needed to sneak by the AR-15-style assault rifle he bought just one week before the attack.

Walt Disney World has yet to comment on this report.

Mateen attempted to purchase military-grade body armor a few weeks before the attack but was denied by a local store.

Had he been able to secure that armor he could have prolonged his attack for even longer as the model he had been hoping to buy is at an 'even higher level than what ordinary police departments supply to their officers' according to investigators.

The other four parks at Disney World - Magic Kingdom, Hollywood Studios, Animal Kingdom and Epcot - would have been far more difficult for Mateen to enter as they have all installed metal detectors.

It is also being reported that Mateen had been spotted at Pulse multiple times by patrons, and would often sit in a corner drinking alone.

Ty Smith told the Orlando Sentinel that he had seen Mateen at least a dozen times at the gay club, and that on occasion he 'would get so drunk he was loud and belligerent.'

He also said that he did not talk much to Mateen but that he did tell him he had a wife and a son and would at times speak about his father.

He was in the area for several days before the attack according to a source who spoke with USA Today, suggesting he had carefully selected his target.

Forty nine people were killed and another 53 were injured early Sunday when Mateen, 29, opened fire at Pulse at little after 2am in what is now the deadliest mass-shooting in American history.

He was eventually shot dead by police following an hours-longs standoff during which he held hostages inside the club but made no demands.

Mateen had previously been investigated by the FBI on two occasions, first in 2013 when he was interviewed by officers twice, and a year later when he was quizzed for a third time.

The initial probe came after he told co-workers that he knew Boston Marathon bombers Tamerlan and Dzhokhar Tsarnaev.

The second investigation concerned possible ties to Moner Mohammad Abusalha, who had grown up in nearby Vero Beach and became the first American suicide bomber in Syria, where he fought with the Nusra Front.

The Tsarnaev brothers came up again on Sunday night when Mateen called them his 'homeboys' during his call to 911 made approximately 30 minutes after he entered Pulse.
