The DNR has already confirmed a sighting, back in 2010 here in Greene County.

They even released pics....
"The chance of encountering a mountain lion today in Indiana is almost non-existent"
"
"One thing to point out is mountain lions are not stalkers," said Gary Langell, the DNR's private lands program manager and developer of the mountain lion policy. "They don't stalk prey. They tend to pick an active game trail, like a deer trail, and wait for a deer to come by. That's typically why you don't see livestock kills from mountain lions. They lay in wait rather than stalk."
"
Without additional evidence, Langell said it's impossible to say if the mountain lion photographed in Greene County is wild or is a formerly captive cat."
"
The DNR occasionally receives reports of mountain lion sightings around the state, but typically the evidence has turned out to be something other than a mountain lion, has been inconclusive, or has proved to be part of an Internet hoax.
Since the policy's inception March 1, 19 mountain lion sightings have been reported. The report in Greene County is the only one confirmed to be a mountain lion.
Langell said two reports were confirmed by biologists as animals other than a mountain lion. Sixteen were designated as "unconfirmed" either because of no physical evidence or because photographs provided were of insufficient quality to identify characteristics of any animal type."
