The Nashville, Tenn., police said Monday that Travis Reinking, the suspect in a quadruple homicide at a Waffle House restaurant on Sunday, is now in custody, according to a tweet. The 29-year-old is believed to have shot four people before another customer wrestled his gun away and he fled. Reinking is from central Illinois and has a history of mental problems, according to media reports. He was wearing nothing apart from a green jacket when he started shooting, and fled the scene wearing no clothing.
