BINGHAMTON, N.Y. (AP) — The mother of one of the two escapees from a maximum-security prison in northern New York says she wants "nothing to do" with her son now that he's the subject of a massive manhunt.

Pamela Sweat of Conklin told the Press & Sun-Bulletin of Binghamton (http://press.sn/1S40rmW ) on Tuesday that 34-year-old David Sweat's childhood was marked by behavioral problems and violent tendencies.

Authorities say Sweat and fellow murderer 48-year-old Richard Matt broke out of Clinton Correctional Facility in Dannemora last weekend by using power tools to cut through steel walls and pipes. They remain at large Wednesday.

David Sweat was sent to prison for killing a sheriff's deputy near Binghamton in 2002.

His mother says she and her son wrote to each other several times a month, but his letters stopped about two months ago.
