Lawyers for the 15-year-old boy (pictured) accused of killing his parents and three siblings in Fall City, Washington, claim his brother committed the crime.
The unnamed teen is accused of massacring all but one of his family members with his father’s Glock pistol in their luxurious $1.4 million home in the leafy city 30 miles from Seattle.
Defense attorney Amy Parker wrote in a Nov. 1 court statement that there are “two versions of events.”
“No one who was involved in this shooting would have escaped without a substantial amount of blood (on them),” he wrote, arguing that there is no mention that the boy had blood on him in 106 pages of evidence.
“Due to the rapid arrest in this case and the narrow focus of authorities, a defense review of the crime scene is necessary.”
Parker said defense attorneys were only allowed into the crime scene for one hour several days after the murders, and requested more time to investigate the house.
“In my experience, law enforcement can and do engage in bias investigations when they believe they have the ‘right’ suspect,” Parker said.
According to detectives, the 15-year-old also attempted to stage the crime scene to lend credence to his story that it was a murder-suicide carried out by Benjamin.
Electrical engineer Mark Humiston, 43, and his registered nurse wife, Sarah, 42, were found dead in the home along with three of their children.
The teen’s three siblings, Benjamin, 13, Joshua, 9, and Katheryn, 7, were killed in the shooting. His 11-year-old sister survived.
The couple were extremely religious: they imposed a highly controlled existence on their five children, which included dictating who they could be friends with and homeschooling them.
The report noted that a black Glock pistol had been placed in the boy’s hand, but forensic investigators found that the gun had not been fired and that blood splatter from a fatal wound to the boy’s face was in the wrong place.
The surviving 11-year-old girl told police that the weapon used to commit the monstrous murders was her father’s silver Glock pistol, which he kept in a small box by the front door, Fox News reported.
He also noted that of all his siblings, his older brother was the only one who knew the combination to access the firearm.
The only surviving 11-year-old daughter played dead before escaping the bloodbath through a “fire window” in her bedroom and ran about a quarter mile to a neighbor’s house.
In disturbing detail, he recalled his brother leaning over the three family members he shot in the hallway before touching their bloody bodies to make sure they were really dead.
Defense attorneys said they were only allowed into the crime scene for one hour several days after the murders and requested more time to investigate the house.
Her older brother then re-entered her bedroom, where she closed her eyes and held her breath as he stood over her bed.
Once her brother left his room and she could hear him upstairs talking on the phone, she used the window to escape before running to her neighbor’s house and ringing the doorbell incessantly, fearing her brother would come looking for her.
The surviving daughter, bleeding from her neck and hand, told neighbors that her family had died at the hands of her own brother before calling the police.
