WARWICK — William R. Keenan, one of four men charged with beating a restaurateur in 2006, has been found guilty in Kent County Superior Court of first-degree robbery and conspiracy.

A jury reached the verdict Thursday afternoon after a few hours of deliberation. Keenan, 21, of 73 Eton Ave. in Warwick, was taken into custody and will be sentenced July 24. Both charges carry a minimum of 10 years in prison.

Konstantino Panteleakis was beaten just before 10 p.m. on April 5, 2006, as he was closing his restaurant, Timmy’s One Bay View Avenue. A masked man carrying a baseball bat scuffled with Panteleakis and three others wearing masks emerged from the shadows, all swinging bats, said Special Assistant Attorney General Thomas O’Brien.

Panteleakis received injuries to his head, back, knees and hands. The assailants stole $3,200 in cash. They split up the money, O’Brien said. The money was never recovered.

The police made four arrests: Keenan; Joseph A. Hulkow, of Providence; Christopher Sylvester of West Warwick; and a 17-year-old from Warwick.

The men apparently tossed their bandanas, gloves and a bat emblazoned with Big Dogz in their haste to flee.

The four were a part of a rap group called the Big Dogz, O’Brien said, which the police confirmed through a MySpace page for the band members. Keenan, or “Killy Bob Bizzle” as he was known, had photos on the site of himself dressed in dark clothing, with a bandana covering his face and wielding a baseball bat, O’Brien said.

Hulkow and Sylvester pleaded no contest to the charges last year and both received 20-year sentences at the Adult Corrections Institution, with 5 years to serve and 15 years suspended. Both will serve 15 years of probation when released. The juvenile received a year at the state Training School in June 2006, followed by probation, according to Michael J. Healey, spokesman for the attorney general’s office.
