A jail warden said Sunday he will ask a judge to move an 11-year-old boy accused of killing his father's pregnant girlfriend from an adult lockup to a juvenile detention center because the jail cannot accommodate the boy.

Lawrence County Warden Charles Adamo said his 300-inmate jail cannot offer proper long-term care for Jordan Brown, of Wampum, who was charged Saturday with using his own 20-gauge shotgun to kill 26-year-old Kenzie Marie Houk.

Houk was eight months pregnant with the child of Brown's father and also had two daughters, ages 4 and 7, who lived together in the rural home where authorities said she was slain as she lay in bed Friday.

Police said the boy then hopped onto a school bus with Houk's oldest daughter. State troopers picked him up at school after tree trimmers called 911 when Houk's youngest daughter told them she thought her mother was dead.
