Mateen originally wanted to attack Disney Springs before Pulse

Pulse gunman Omar Mateen planned to shoot up the Disney Springs resort in Orlando, not the gay nightclub where he murdered 49 people.

Prosecutors made the revelation during closing arguments Wednesday in the case against his widow, Noor Salman, who’s charged with helping him plan the mass shooting.

Mateen declared his support for ISIS on the June 12, 2016, massacre, before he was killed in a firefight with police.

The killer may have been scared off by a heavy Orange County sheriff’s department presence around the complex, federal prosecutors said in court.

In opening arguments, prosecutors accused Salman of helping Mateen plan out an attack on Pulse.

Assistant U.S. Attorney Sara Sweeney told the jury it wasn’t important that Salman didn’t know her husband switched to Pulse.

“She doesn’t have to know that his initial target didn’t work out,” she said in comments carried by the Orlando Sentinel.

Prosecutors uncovered cellphone evidence leading up to the trial that showed Mateen was near the resort as well as another club, EVE Orlando, the Sentinel reported.

Salman faces life in prison if she’s convicted of helping her late husband.

Earlier this week, her lawyers requested the case be dismissed or a mistrial declared after receiving information that Mateen’s father acted as an FBI informant during the 11 years leading up to the mass shooting.
