Police have identified a person of interest in the Saturday homicide of the Executive Director of the Brownsville Museum of Fine Art at his home at 1400 Flor de Mayo in Brownsville.
Officers say they are looking for 19-year-old Ernesto Ivan Martinez of Brownsville, who at one point was Barry Horn's partner and lived together until they had a falling out.
Police said Martinez is not a suspect in the case but simply a person of interest who they say may have first hand information on the fatal stabbing.
Action 4 has learned Martinez has a criminal past.
He spent 5 months in jail on criminal trespass and theft charges.
He was released in April of this year.
As police investigated the scene, they said they noticed several of 59-year-old Horn TMs items were missing, including his car, which they believe might be in Martinez TMs possession.
The car is a four door, grey 2008 Hyundai Sonata with Texas license plates JWM-350
Meanwhile, an ex-coworker told Action 4 Barry Horn will be missed greatly because he was an extraordinary gift.
Dr. Bill Strong said Horn as the "go to guy" when they worked together at the University of Texas at Brownsville.
For more than four years, Horn was the Director of Development and worked hand in hand with Strong, just before moving on to the Brownsville Museum of Fine Art nearly a month ago.
"He stood out right away as the guy who could do impossible things so whenever we needed the impossible done, people would say call Barry," he said.
Strong said Horn was greatly appreciated by those around him.
So when the news came that he was stabbed to death inside his Brownsville home on Saturday night, he was surprised.
"I was of course shocked that he died, then shocked at the way, particularly because he was such a gentle soul," Strong said.
He added that Horn was often involved in one way or another in any cultural event imaginable, not just in Brownsville but the entire Valley.
He says this time should serve as a thankful reflection on his life.
"I dont wanna focus on his end because his life was extraordinary and like I said, he touched a lot of people in the valley through all the work he did."
