Man calls family to say he killed his friend, 3 months later charged in connection to the murder

A 29-year-old Indiana man called a relative to say he may have killed his friend, but it took three months for police to charge him in connection to the killing.

On March 21, police responded to a 911 call from a relative saying Matthew D. Castro, 29, called and said he may have killed his friend, authorities said.

When police arrived at the scene, Castro was outside the house with blood on him, officials said.

Police said Castro told them, “my friend tried to beat …” and then made a gagging sound, authorities said.

Inside the house, police said they found a bruised and bloody Michael Overton, 42. Overton was non-responsive and officers said he was pronounced dead at the scene.

According to the autopsy report, it revealed “multiple significant blows to Michael Overton’s head” and “a dislocation of the joint at the C1 vertebrae.”

At the time, Castro was arrested on charges unrelated to the investigation, which included three counts of battery with bodily injury to a public safety official, two counts of battery against a public safety official, two counts of intimidation and one count of resisting law enforcement, authorities said.

The Northwest Indiana Times reported a family member told police Castro and Overton often spent time together.

Police said they obtained a recording of a call Castro made in jail, which he said, “he thought he beat Michael Overton up and the next thing he knew, the police were at his residence.”

Castro has now been charged in connection with Overton's death, police said.
