Officials in White County have not released the names of the three people killed by a lone gunman yesterday at a Monticello business. Police were called to Jordan Manufacturing late yesterday morning, according to WLFI-TV. White County Sheriff Pat Shafer confirms two Hispanic men were pronounced dead at the scene of apparent gunshot wounds. A Hispanic woman died a short time later at IU Health White Hospital. Witnesses tell the TV station one of the men was the shooter and say he came to the business looking for his ex-wife. She was at lunch when he arrived, according to her coworker, who says he hid outside and waited for her to return. When she and her boyfriend pulled into the parking lot, the witness said the man jumped from behind a tree, spoke to the couple, shot the man, shot his ex-wife then turned the gun on himself. Authorities are still investigating.
