Two men have confessed to their involvement in a fatal attack on an 18-year-old they believed to be gay.

Jonathan Echevarria pled guilty this week to first-degree manslaughter, with Queens Supreme Court Justice Joseph Zayas indicating he will sentence him to 18 years in prison.

Nolis Ogando pleaded guilty first-degree gang assault and will received an eight-year sentence.

In March 2011, Ogando, Echevarria and four other men, all believed to be members of a local gang, crashed a party attended by Anthony Collao in Queens that was hosted by two gay men.

The group, all teenagers at the time, started trashing the home—breaking windows, writing anti-gay words on the walls and yelling homophobic slurs at Collao, who was straight.

Collao left the party but the men chased him into the street. Yelling more slurs, they threw him to the ground, then punched, kicked and bashed him with a pipe and cane, before robbing him and leaving him for dead.

Two days later Anthony Collao succumbed to his injuries.

The four other assailants had previously pleaded guilty to charges of second-degree assault or first-degree manslaughter.

“The last two defendants in this case have now admitted their roles in this heinous attack that cost a young man his life,” Queens district attorney Richard Brown said.

"This was a horribly brutal and unprovoked attack. The victim had just left a birthday celebration and was chased down as the defendants yelled anti-gay slurs,”
