The Idaho Commission for Pardons and Parole has revoked parole for Steven Wolf, returning him to prison to continue serving a 30-year term for the 1976 slaying of Enrico Flory, Boise's "cat man of Bella Street."

Olivia Craven West, executive director of the parole commission, said the revocation came Tuesday after it was learned Wolf, 30, tested positive for amphetamines in a routine urinalysis after almost 13 months on parole.He also committed other violations, Craven West said, including changing jobs without permission.

A new release date of July 25 was tentatively set, and the date for completion of Wolf's parole was extended from November 1996 to December 1997, Craven West said.

He was charged with first-degree murder in September 1976 and pleaded guilty to second-degree murder in November 1978, more than two years after the June 3, 1976, death of Flory.

Prosecutors alleged Wolf led a group of teenagers who robbed and killed Flory, 77, in his North End home on Bella Street, which he shared with several cats.

Besides the 30-year sentence for Flory's slaying, Wolf received an additional year in June 1988 after pleading guilty to a drug possession charge at the Idaho State Penitentiary.

Meanwhile, the parole commission on Tuesday set a tentative release date of Jan. 19, 1995 for Jonathan Mack LaFon of Pocatello, who pleaded guilty to first-degree murder in the 1978 slaying of a Tremonton, Utah man.

LaFon, 32, who received an indeterminate life sentence for the slaying from 6th District Judge George Hargraves, will be placed on "institutional parole" from that term on Jan. 21, 1993. Craven West said he then will serve at least two years of five-year sentence he received for possession of a controlled substance in prison.

Phillip Edward Borup, 37, was found shot to death on Feb. 19, 1978, in the Mink Canyon area 10 miles north of Pocatello. LaFon was arrested in Twin Falls two days after the shooting.
