Texas man allegedly murdered DJ girlfriend in Colombia, stuffed body in suitcase and tossed in dumpster

A married Texas man is suspected of killing his Colombian girlfriend by strangling her and stuffing her into a suitcase that he then tossed into a dumpster.

It was determined Trespalacios, who was a popular DJ with 16,000 followers on Instagram, was killed by "mechanical asphyxia" or "strangulation." Andrew Mark Miller is a writer at Fox News. Find him on Twitter @andymarkmiller and email tips to AndrewMark.Miller@Fox.com.

John Nelson Poulos, the 35-year-old boyfriend of Trespalacios who had met her on a dating app last year, left Colombia for Panama days before her body turned up. He was arrested Jan. 24 as he was about to board a flight to Montenegro, a country that does not have an extradition agreement with Colombia or the United States.
