A suspect has been taken into custody in the slayings of four people, including an 8-year-old boy, who were found fatally shot in a southeast OH home Wednesday.
The stabbing victim returned home to find the gruesome scene and was then stabbed in the head and neck by the suspect, Lawless said.
A fourth adult who was stabbed at the home fled and was flown to a hospital.
Officials had launched a massive manhunt for 23-year-old Aaron Lawson, who is charged with multiple counts of murder.
Lawless mentioned that the people killed were somehow related, and Lawson was known or related to everyone in the residence as he spent a lot of time there "visiting and socializing". Although he may still be armed, Sheriff Lawless has said that officers believe the murder weapon has been recovered.
Around 7:30 Wednesday evening, sheriff's deputies had been called to a trailer home where three adults were dead and a 7-year-old boy was missing. Sheriff Lawless has said that the other victims are all adults and are "related in some fashion".
The sheriff wouldn't discuss any potential motive or the chronology of the slayings, and he declined to disclose what Lawson said to the arresting officers.
Deputies chased Lawson before he crashed his vehicle into a ditch and ran into the woods, the sheriff said.
Police have identified a person of interest in the case, Aaron Lawson, 23.
None of the dead adults or injured victim has been identified.
Anyone with information is asked to call the sheriff's office at 740-532-3525.
Lawrence County Sheriff Jeffery Lawless says Lawson is an outdoorsman and hunter but seemed "worn out from being out in the elements" and didn't flee when confronted Friday.
"Devin was widely liked by all the staff and students", said Wes Hairston, superintendent of Rock Creek Local Schools.
The initial report about the slayings - violence against multiple people found at properties of related residents - recalled details from a still-unsolved homicide case that rattled rural southern OH a year ago.
Lawson was being questioned by investigators Friday and could face more charges, the sheriff said.
The deaths on Wednesday occurred roughly 40 miles (64 kilometers) southeast of the Piketon area, where eight people from the Rhoden family were found shot to death in four homes in April 2016.
