Police in Arkansas are searching for a suspect in the deaths of a couple who investigators said were attacked while on a wooded walking trail with their two young daughters.

Police say the suspect accused of killing the couple as they hiked with their 7- and 9-year-old daughters is still at large.

A mother and father were killed this weekend at an Arkansas state park while they were out hiking with their young daughters, state police said. A manhunt is underway for the suspect.
