A murder-suicide in Hawkins county left two young people dead Tuesday afternoon.
The sheriff's office responded to a shooting call in Church Hill. Deputies say they found two people with gunshot wounds to the head inside.
They say 20-year-old Thomas McCracken shot his 21-year-old girlfriend Sierra Nichole Smith in the head, then shot and killed himself. The wound did not immediately kill Smith. Deputies say she later died at the hospital.
The couple's 3-month-old baby and McCracken's grandmother were home at the time.
Deputies are not sure why McCracken shot his girlfriend. They are continuing their investigation.
