Family members of a woman killed by a teenager who drove the wrong way on a Kansas highway say more should have been done to keep him off the road after he told deputies he had taken LSD.

Two women and 16-year-old Dominic Stolfi were killed in the collision Sunday morning on Kansas 254, hours after Stolfi said he had taken the hallucinogenic drug.

Butler County Sheriff Kelly Herzet says deputies didn’t have grounds to arrest the boy.

His 16-year-old friend, who also allegedly took LSD, was taken by ambulance to a hospital, while Dominic’s father took him home.

The Wichita Eagle reports Dominic later drove the family’s Ford Explorer into a collision with a car driven by 27-year-old Lisa Hardy, killing her and her 52-year-old passenger, Nancy Ross.
