DANNEMORA – A massive manhunt is still underway as police and DOCS personnel search for convicted killers Richard Matt and David Sweat, the two men who escaped from an upstate prison over the weekend.

The escapees' complex plot – worthy of Hollywood fodder – led the two through steel walls, down four stories of service corridors and along a labyrinth of pipes and tunnels that would eventually lead them to a manhole cover blocks from the Clinton Correctional Facility in the Village of Dannemora.

Currently, authorities are conducting active searches throughout three upstate counties and have received more than 150 tips in the case, according to the New York State Police.

Prison administrators are left scratching their heads, and even Governor Andrew Cuomo admitted, “We are left with more questions than answers at this point.”

Meanwhile, New York has placed a bounty the sum of $100,000 on the heads of the two felons if and when they are brought back to justice to answer to new escape charges.

Matt and Sweat resided in adjoining cells and evidently used power tools to cut through a concrete and steel wall at the correctional facility, authorities said. The pair are the first prisoners to escape New York's most populated prison. The facility houses more than 2,900 of New York's most dangerous prisoners.

Opened in 1845, “Little Siberia” is also home to Ganesh R. Ramsaran, the New Berlin man who made local headlines for murdering his wife in 2012.

Ramsaran allegedly plotted an escape that was quickly foiled by corrections officers.
