NEW CASTLE, Pa. (AP) An 11-year-old boy charged with killing his father's pregnant fiancee will be moved from a county jail to a juvenile facility under a court order issued Tuesday.

A judge agreed that it is in Jordan Brown's best interest to be housed in the Allencrest Juvenile Detention Center northwest of Pittsburgh. Brown will remain charged as an adult in the shooting death of 26-year-old Kenzie Marie Houk, though his attorney said he will ask to have the case moved to a juvenile court.

"What we have learned is that under Pennsylvania law he can continue to be prosecuted as an adult and be housed in a secure juvenile detention center," defense attorney Dennis Elisco said.

Brown is accused of shooting Houk in the head Friday, killing her and her unborn baby boy.

He's in a cell isolated from the adult inmates in Lawrence County Jail. Elisco said his client will be moved to the juvenile center Wednesday morning.

Hundreds of friends and family members lined up Tuesday evening outside a funeral home in New Castle for a public viewing of Houk.

Houk's immediate family was allowed to see the body of the 7-pound infant she was to deliver in just a few weeks, Houk's uncle, Williard Houk, told reporters. The baby was named Christopher, after his father.

"It was a hard thing because they let the immediate family view the baby and it was just a hard thing knowing (Houk) was so close to being delivered," Willard Houk said.

Authorities believe the killing was premeditated. They say Brown went downstairs with two guns but returned upstairs after Houk's 7-year-old daughter saw him; they believe he then hid a gun in a blanket and went back downstairs to Houk's bedroom and shot her in the back of the head.

Later, the 7-year-old girl told police she saw the boy drop something on the ground from his pocket before they got on the school bus. Police said they found a spent shotgun shell in the same spot.

Earlier Tuesday, Houk's mother said the boy had been threatening her daughter for at least two months and often gave her a hard time, especially when his father wasn't around.

Brown and his dad, Christopher Brown, lived with Houk and her two small daughters in a farmhouse in the rural western Pennsylvania town of Wampum.

"It's been at least two months that he's made the threats," Debbie Houk said, adding that Jordan "just bucked her (Kenzie) a lot when his dad wasn't around."

"Chris was good about it. He tried. He told him, 'Don't you ever disrespect her,'" Debbie Houk added.

Debbie Houk said Jordan, a hunter, knew a lot about guns and was a good shot. On Valentine's Day, he beat out many older and more experienced hunters at a turkey shoot.

"I'll never cook that turkey. It's the same gun that killed my daughter," she said. "So he knew what a gun did. He knew the dangers of a gun."
