A 19-year-old is in police custody after he allegedly stabbed his own father to death at their shared home. On Wednesday, January 21, police were called to a neighborhood in Mobile, Alabama, where they found Mark Prince dead in the front yard. He had reportedly been stabbed multiple times, per CBS affiliate WKRG. It is unclear if the stabbing occurred inside or outside of the residence. Mark's son, Samuel Prince, reportedly called his mother, who then called 911. When police arrived, the 19-year-old was still at the scene. He was later arrested in connection with his father's death.
