VIDEO: A Texas Man Called ONSTAR to tell them that he was off his Meds and was Planning a Bloodbath.

SAN ANTONIO - Several lives very well may have been saved when a man called Onstar and threatened to kill himself and others if they interfered.

Known for its road side assistance, help with directions, and emergency services, Onstar may have saved many people's lives Friday night after a New Braunfels man said something very scary to the Onstar operator.

“He stated that he's been off his medication and that he was down in San Antonio and he wanted to cause a blood bath,” said Sgt. Daniel Anders from the San Antonio Police Department.

Police were called and Onstar was able to tell them exactly where to find the man. Police confronted the man at a Lowes parking lot on the Northeast Side near I-35. The man's identity has not been release.

“We were able to talk him out of the vehicle peacefully,” Sgt. Anders told News 4.

Officers handcuffed and questioned the man and a search of his vehicle revealed two shotguns with ammunition.

Police told News 4 the man's wife had called earlier in the evening, warning them of his mental issues.

Officers say they are relieved that a possible tragedy was averted by a push of a button.

“It worked for this situation and everyone went home safely,” said Sgt. Anders.
