Luz Hernandez,33, was reported missing Monday. Hudson County, New Jersey Prosecutor Esther Suarez confirmed on Friday that one man has been arrested in connection with her death, and an arrest warrant has been issued for another.

Santana was arrested at a motel in Miami in the early hours of Friday morning. He is being detained in Florida pending extradition to New Jersey. 

Officials urged anyone with information about Lopez to contact the Hudson County Prosecutor’s Office.
