LONDON, Ky. (AP) — As a grueling manhunt stretched into a third day Monday for a suspect in an interstate shooting that struck 12 vehicles and wounded five people, authorities vowed to keep up a relentless search as the stress level remained high for a rural area where some schools canceled classes.

As the search continues a second night for the man suspected of injuring five people when he opened fire on Interstate 75, many area schools have decided to close Monday and law enforcement are warning the rural Kentucky community to take safety precautions.
