The "Son of Sam" is in Albany.
A report in the Times-Union says David Berkowitz, who killed six people and wounded seven others in the mid 1970's, was to undergo emergency surgery on Monday for a heart ailment.
Berkowitz is serving a 25-to-life term for each of the murders, and is doing his time at the Shawagunk Correctional Facility in Ulster County.
And, there are also reports that David Sweat, who made headlines with his 2015 escape from the Clinton Correctional Facility, is on a hunger strike to protest his move to Attica.
Prison officials are said to be seeking a court order to have him fed through a tube.
