Federal prosecutors want to seize about $10,000 from the prison account of 98-year-old ex-mobster they say boasted about killing 60 people in his life.

John "Sonny" Franzese's son Michael tells the Daily News (http://nydn.us/1jWiG1o ) his father needs the money to buy eye drops, soup and sometimes ice cream. He says family members have put up the cash.

Sonny Franzese was convicted of extorting a strip club while he was underboss of the Colombo crime family. He's at a Federal Medical Center in Massachusetts.

Franzese once lived the high life — hanging out with Frank Sinatra and Sammy Davis Jr. at New York's Copacabana nightclub. He also had a stake in the porn film "Deep Throat."

Prosecutors contend the seizure would still leave Franzese $250 in spending money.
