MONTGOMERY COUNTY, Ind. (WLFI) -- Tuesday's bank robbery in Linden is begging more questions than answers.
Around noon Tuesday a man went into the Hoosier Heartland State Bank, he showed a gun, demanded money and fled northbound.
With two other area bank robberies unsolved in the past month, and another in May, neighbors and authorities are asking if there are any connections.
"He just looks a crazy person," said Montgomery High School freshman Benjamin De La Cruz.
Cruz said his school was on a soft lockdown because of the bank robbery at the Hoosier Heartland State Bank.
"So it was essentially during class periods," said De La Cruz. "You could not go into the hallways and you had to wait until the passing period to do stuff."
Outside the school, police were scouring the area for a suspect with a fake beard.
"I mean it's pretty unique," said De La Cruz. "I've never seen something like that."
But it actually had happened before, at least two other times.
On May 10th, a man in a fake beard robbed the Centre Bank in Hillsboro.
Months later on August 5th, someone robbed Centier Bank without a disguise.
But it happened again on August 26th, at the Regions Bank in Lafayette.
Then the one in Linden on Tuesday.
Police still can't confirm which, if any, of the robberies are connected.
"I mean it's not a funny thing, but the look of them is funny," said Lafayette's Cynthia Ralston.
Another commonality is all four are unsolved.
"It's a pretty safe town in my opinion, so it's kind of weird to hear of so many in succession," said Ralston.
In all four cases, the robbers fled on foot, but there are other discrepancies too, like whether or not they showed a weapon.
Ralston said she doesn't see the connection.
"They actually, to me, they look different," said Ralston.
Ralston said she wished these bank robberies didn't happen in her city.
"If there is a cop nearby that gets the call, if they are running on foot or even if they are in a car, then a chase can happen," said Ralston. "Somebody could get hurt them or somebody else."
In all cases, nobody was hurt.
