NEW YORK—A jury convicted a Brooklyn man of manslaughter and on hate crimes charges Oct. 5 for an attack on a gay victim at a remote New York City beach that led to the victim’s death.

John Fox was one of four young men implicated in the assault on Michael Sandy, who was ambushed and chased into traffic during a mugging a year ago. A car struck Sandy as he fled onto Brooklyn’s Belt Parkway, fatally injuring him.

The jury acquitted Fox of a murder charge, but found him guilty of second-degree manslaughter and attempted robbery. Jurors also found that the offense amounted to a hate crime.

Fox, 20, and three others are accused of going into an Internet chat room frequented by gay men last October to find a potential robbery victim.

A second jury is separately considering murder, manslaughter and hate crimes charges against a second member of the group, Anthony Fortunato.

A third man accused of participating in the attack, Ilye Shurov, is to be tried separately. A fourth man, Gary Timmins, who was 16 at the time of the killing, pleaded guilty to attempted robbery and testified for prosecutors.
