According to Indianapolis Star on June 12th:

The news reports from New York of an underground escape by dangerous inmates from a prison built before the Civil War has an all too familiar ring to people in the Indiana prison system and the community that is home to the state’s oldest prison.

That’s because something similar happened nearly six years ago at the Indiana State Prison in Michigan City, where escaping inmates crawled through hundreds of yards of utility tunnels to emerge through a manhole cover to temporary freedom.

“It does ring a bell when I hear about the one in upstate New York,” said Michigan City Chief of Police Mark Swistek, whose department joined the manhunt after the 2009 escape of three inmates who emerged from a manhole on West 10th Street. “As far as the age of the prison, there are a lot of similarities on how they actually escaped in that.”

In upstate New York, a massive manhunt is underway for two prisoners who escaped the maximum security Clinton Correctional Facility, near the Canadian border. The two broke through bricks, crawled through a steam pipe and emerged through a manhole outside the 170-year-old prison. Their escape was discovered Saturday.

The Indiana State Prison, like the one in New York, is old — built in 1850. It has networks of underground tunnels and pipes leading outside its walls. In a review of the 2009 incident, its “outdated” design was found to have contributed to the escape of convicted rapist Lance Battreal and convicted murderers Mark Booher and Charles Smith. It took nearly two weeks before all of the escapees were caught.

In the wake of that breach, three Michigan City prison employees were fired and improvements were made to “button up” the security gaps. Tunnels were blocked with steel bars. And James Basinger, deputy commissioner of the Indiana Department of Correction, said prison officers are now assigned to check some of the tunnels for “unauthorized activity.”
