President Donald Trump's promise for the “largest deportation program” in U.S. history has not only led to a surge in Immigration and Customs Enforcement arrests in Maryland and the rest of the country, it’s shifted the agency’s tactics as well.

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.

State police identified the victims on Sunday as 43-year-old Clinton David Brink and his 41-year-old wife, Cristen Amanda Brink. In a statement issued on Sunday, the Arkansas State Police said the couple was killed while out hiking with their two daughter, ages 7 and 9, who were not injured in the incident.
