The elder Han’s battered and bleeding body was found around 2 p.m. Monday by his wife in their Ambler home. He was unconscious when police arrived and was pronounced dead at the home a short time later.

Authorities have not said what sparked the attack but noted there were signs of a violent struggle and bloodstains throughout the living room area where the victim was found. Detectives discovered a box-cutter near Han’s body, and a butcher knife with a broken blade tip was found in the kitchen.

When detectives interviewed Maximillian Han on Monday, they noticed bruising, swelling, and cuts to his right hand, authorities said. At first, he told detectives he had left the home after becoming angry with his father, but authorities say he later admitted to the beating and selling his father’s cellphone for $20 at a nearby mall.

An autopsy determined Jinhan Han died from multiple blunt and sharp injuries. His death has been ruled a homicide.
