The last of seven Long Island teenagers involved in the 2008 stabbing death of an Ecuadorean immigrant has been sentenced to five years in prison.

Marcelo Lucero (mar-SEHL'-oh loo-SEHR'-oh) was stabbed in a confrontation near the Patchogue (PACH'-awg), N.Y., train station. The killing focused the national immigration debate on Long Island.

Nicholas Hausch, who's now 19, was a key prosecution witness in the trial against co-defendant Jeffrey Conroy.

Hausch said Conroy admitted inflicting what turned out to be the fatal blow.

Conroy was the only defendant to go to trial. He was convicted of manslaughter and is serving a 25-year prison term.

The others, including Hausch, pleaded guilty to gang assault and other charges and are also in prison.
