A Brownsville man considered a person of interest in the murder of museum director Barry Horn, is back in the United States.
U.S. Customs and Border Protection officers at the B&M International Bridge took custody of Ernesto Ivan Martinez, 19, wanted on an arrest warrant for felony auto theft.
Federal authorties took custody of Martinez and turned him over to Brownsville police sometime Monday.
CBP officers used a federal database to confirm Martinez as a match on an outstanding arrest warrant from Brownsville Police Department.
Martinez, who is from Brownsville, was referred to secondary for further inspection and verification of the outstanding warrant.
Once CBP officers confirmed Martinez was the same man considered as a person of interest in Horn's death, they detained him and turned him over to Brownsville police officers.
Martinez was transported to the Brownsville Police Department jail where he remains jailed. There is a possibility he will be arraigned this morning on the felony auto theft charge.
"CBP officer working with the Brownsville Police Department arrested this subject wanted for auto theft from the Brownsville Police Department. We worked closely with the Brownsville Police Department to bring this wanted person to face pending charges in the U.S.," said Michael Freeman, CBP Port Director, Brownsville.
Martinez was captured Sunday in Matamoros by the Policia Ministerial del Estado after the department received information from Brownsville police that Martinez was thought to be in the Mexican border town.
Horn, 59, was found dead in his west Brownsville home at 1400 Flor de Mayo Saturday afternoon. Police said he'd been stabbed to death and evidence indicates there was an apparent struggle between Horn and his killer.
His body was discovered by a co-worker when Horn failed to show up at the BMFA in preparation for Saturday night's fundraising gala.
Investigators say Horn's grey 2008 Hyundai Sonata with Texas license plates JWM 350 was missing from his home as were several other personal items.
Police say Martinez had lived with Horn until they had a falling out. They also believe Martinez took Horn's car.
