MANAGUA, Nicaragua -- Nicaraguan police have arrested an alleged MS-13 gang member who recently was added to the FBI's "Ten Most Wanted Fugitives" list as a suspect in the 2010 killings of his 19-year-old girlfriend and her toddler son in New York state.

The 21-year-old suspect was added to the FBI's "Ten Most Wanted Fugitives" on Wednesday, the first MS-13 gang member to make the list.

Prosecutors allege the El Salvador native lured Vanessa Argueta and her 2-year-old son to the woods of Central Islip, N.Y. in February 2010, where two other gang members shot them to death.
