Gang killings in a New York City suburb are getting the attention of Donald Trump.

In an interview with Time magazine for his "person of the year" profile, Trump explained his tough view on illegal immigration by citing news coverage of the killings of five Hispanic teenagers in Brentwood.

Police have said that the slayings are likely the work of the MS-13 street gang. It has roots in El Salvador and has been linked to at least 30 killings on Long Island since 2010.

Trump said some of the killers were in the U.S. illegally.

Investigators say that's true, but some local advocates for new immigrants say they are worried that a Trump-led crackdown will go far beyond the criminals he means to target.
