US: 15-year-old Accused Of Killing Parents And 3 Siblings

In a shocking incident, a 15-year-old boy allegedly killed his parents and three siblings in Washington state.

Electrical engineer Mark Humiston, 43, and his wife Sarah, 42, a registered nurse were found dead at their home in Fall City, 30 miles away from Seattle along with three of five children.

The boy who killed the parents called 911 at 4:55 am saying his family had died. He claimed that the slaughter was part of a murder-suicide plot by his younger brother Benjamin who was caught watching porn the previous evening.

The teenager allegedly placed the Glock pistol in the brother’s hand but forensic investigators spotted that the weapon had not been fired and the blood spatter to the boy’s face was in the wrong place. The 11-year-old sister of the teenager survived the massacre by running to a neighbor’s home while the youngest-year-old Joshua and 7-year-old Katheryn died.

Mark suffered four gunshot wounds and was found at the bottom of the stairs. Sarah has two bullet wounds to the head and was found in her ensuite bathroom.

The eldest son was arrested at the scene and is now facing five first-degree murder charges and one count of attempted murder. The couple was extremely religious and imposed a highly-controlled existence on their five kids.
