Former welterweight Luis Resto has acknowledged that the beating he gave the late Billy Collins Jr. in 1983 -- in which, over 10 rounds, he pounded Collins with tampered gloves that each had two inches of padding removed -- was even worse than previously believed.

Resto, at a news conference on Thursday in New York, acknowledged that the tape used to wrap his hands in that fight had been soaked in plaster of Paris, giving him a pair of hardened casts underneath his unpadded gloves.

Collins suffered from blurred vision and depression after the June 16, 1983 fight. He died in a car accident about nine months later.

The admission, which Resto made to Collins' widow, Andrea Collins-Nile, last year during the filming of a documentary about the scandal, has led to a motion to re-open a civil suit against the State of New York over its failure to prevent the beating. The legal filing was also announced Thursday.

Eric Drath, who directed "Cornered," the documentary about the fight and its tragic aftermath, said it was a "heinous and tragic crime" that needed to be retold, according to The (Nashville) Tennessean.

"It happened in a much more brutal way" than had previously believed, Drath said. "Worse than bare knuckles, it was plaster."
