NEW YORK—Three men convicted of beating a gay man and then chasing him onto a highway where he was struck by a car and killed were sentenced to prison Nov. 20, prosecutors said.

All three had been part of what prosecutors called a hate-inspired robbery scheme.

On Oct. 8, 2006, they found Michael Sandy in an Internet chat room frequented by gay men, lured him out to Brooklyn’s remote Plum Beach with a promise of a date and then attacked him. When Sandy tried to escape, he was hit by a car on the Belt Parkway.

Anthony Fortunato, 21, who had told jurors they shouldn’t convict him of a hate crime because he’s gay was sentenced to seven to 21 years in prison for second-degree manslaughter as a hate crime and attempted petit larceny.

John Fox, 20, was sentenced to seven to 21 years in prison for second-degree manslaughter as a hate crime and attempted robbery as a hate crime.

Ilya Shurov, 21, who pleaded guilty, was sentenced to 17 1/2 years in prison for second-degree manslaughter as a hate crime and attempted robbery as a hate crime.

A fourth man, Gary Timmons, had already pleaded guilty to attempted robbery as a hate crime and testified in the case in exchange for a four-year sentence.
