A South Texas husband and wife have been shot to death in their home and a former business partner of the man has been arrested in the killings.

San Antonio police on Thursday did not immediately release the name of the suspect.

A coroner identified the victims as 52-year-old Robert Snyder and 50-year-old Beatriz Snyder. Police say their 20-year-old daughter jumped out a second-story window to escape Wednesday night's gunfire.

Police Chief William McManus says the trio and a business associate were at the residence when the armed former partner arrived. Police say the business associate managed to disarm the suspect following the shootings.

Officers located the suspect, who had blood on this clothing, at a nearby shopping center.

Police did not immediately release a possible motive in the attacks.
