Ernesto Ivan Martinez, 20, was arraigned Wednesday on charges of first-degree murder, second-degree burglary and state-jail felony theft in connection with the death of Brownsville Museum of Fine Art Director Barry Horn.

Brownsville Municipal Court Judge Ben Neece denied Martinez bond on the charge of first-degree murder on the recommendation of Cameron County Assistant District Attorney L. J. Rabb.

Neece set a $10,000 bond on the charge of theft and a $25,000 bond on the burglary of habitation charge.

During the hearing Wednesday morning, Neece read the allegations against Martinez from the affidavit for warrant of arrest:

"It is said that you gained entry into Mr. Horn’s house through [through a bathroom window near] the rear of the residence and that you had previously entered, on the 22nd [of October], which was the burglary, and stole a television, and … on the 24th at approximately 12:45 [a.m.], you have possession of a knife and as you walked into the bedroom of Mr. Horn you attacked him with this knife and stabbed him numerous times, several stab wounds to his chest, his back and his head area, and he died there somewhere in the hallway. Apparently, after that, you took his keys and stole his vehicle and [Horn] was located later by a co-worker at about 12:50 p.m. on the 24th and they called the emergency personnel, but he was dead. And the preliminary cause of death is stated as multiple stab wounds."

The hearing came three days after Brownsville Police took Martinez into custody.

U.S. Customs and Border Protection officers took custody of Martinez on Monday after he was escorted into the U.S. from Mexico by Brownsville police officers, according to a CBP news release. The suspect had an outstanding arrest warrant from the Brownsville Police Department for theft of a Hyundai Sonata, the license plates of which were registered to Horn, Neece said.

Chief First Assistant District Attorney Charles E. Mattingly Jr. thanked Mexican authorities for their cooperation and assistance in apprehending the suspect and the Brownsville Police Department for its efforts in securing Martinez’s return to his jurisdiction, according to a news release from the district attorney’s office.

Horn, 59, was discovered by a co-worker about 1 p.m. Oct. 24 in his home at 1400 Flor de Mayo after he did not show up for work in preparation for a museum fundraiser that was being held that evening, Brownsville police said.

Before joining the museum, Horn held several posts at UTB/TSC, beginning in 2000, when he served as manager of the Jacob Brown Civic Center. He then became director of Development and in 2004 he was promoted to associate vice president for Development. He left the university in 2008, according to a news release from the UTB/TSC Office of News and Information.

Horn was also involved in a number of civic projects: helping the city earn an All-America City Award in 2001, the restoration of the Immaculate Conception Cathedral and establishing Symphony in the Park that benefits the Brownsville Literacy Center, the news release said.

Visitation for Horn was Friday at Sacred Heart Catholic Church, located at 602 E. Elizabeth St. in Brownsville. A rosary followed.

Services were held at 10 a.m. Saturday at the church, followed by a private burial.
