After hours of searching, Elkhart City Police arrested the suspect in a Cass County homicide Friday night.
Around 1:30 p.m., police were called to the 19,000 block of U.S. 12 in Mason Township.
When they arrived, they found Martha Sexton stabbed to death.
"She was in the process of moving, talking to her new landlord and he heard something about a knife and then a phone went dead and he contacted law enforcement," said Cass County Sheriff Joseph Underwood.
Police say Sexton and her brother, 59-year-old Edward Hensley, got into an argument at the home where they both lived with family.
Their niece had been on her way to break the fight up.
"I was coming to prevent something of this nature here," said their niece Cynthia Hunt.
When police arrived, Hensely had already fled the scene.
They called in extra patrols to help search the nearby woods.
"Michigan State Police is close, they were able to contact their division with a helicopter," Underwood said. "They also brought in their emergency services team."
After several hours, police found Hensley in Elkhart County.
He's being charged with open murder in Cass County.
Hensley has no criminal history locally, but family members say he was known for being hot-headed.
Now they're trying to cope with the difficult loss of Sexton and the arrest of Hensley.
"My family's very devastated," Hunt said. "She didn't deserve anything like this."
Police say it appears Hensley was drinking before the afternoon stabbing.
