A pilot and his 8-year-old daughter were killed when their small plane crashed into an in-law's house near a southern Indiana airport, authorities said.
Indiana State Police spokesman 1st Sgt. Dave Bursten said Monday that a preliminary crash investigation leads "us to believe that this was an intentional act."
Monday's crash killed Eric Johnson, 47, of Bedford, and his daughter Emily, he said. The plane crashed into the residence of one of Johnson's in-laws, Vivian Pace, Bursten said.
Authorities will not know for sure whether the crash was intentional until the National Transportation Safety Board completes its investigation, which could take up to a year, Bursten said.
