RENO, Nev. (AP) - Convicted murderer and rapist James Biela grew
up in a poor, abusive and "frankly bizarre" household where his
father routinely beat his mother and the children cowered in fear,
sometimes using a bucket in their bedroom as a toilet, jurors were
told Friday.

The Washoe District Court jury trying to decide whether to
sentence the 28-year-old Sparks man to death for the
killing of Brianna Denison heard testimony from a psychiatrist, his
mother and siblings about his traumatic childhood.

The seven-woman, five-man jury convicted Biela Thursday of
first-degree murder, kidnapping and three counts of sexual assault
in a string of attacks that began in October 2007 near the campus
of the University of Nevada, Reno and culminated in Denison's
strangulation in January 2008.

At a sentencing hearing that will resume Tuesday morning, his
public defenders tried to persuade the same jury to spare his life
and send him to prison for life with no chance for parole based on
mitigating factors including his difficult upbringing.

Biela's father, Joseph Biela, engaged in daily behavior that was
"unusual, abusive and frankly bizarre," Dr. Melissa Piasecki
said.

"Verbal and psychological abuse was pervasive in the house,"
Piasecki said about the apartment where James Biela lived in the
Chicago area with his mother, father, brother and two sisters.

Biela's mother, Kathy Lovell, "bore the brunt of the physical
abuse," she said, suffering broken teeth and ribs, and undergoing
wrist surgery due to injuries from being bound so many times. She
also said earrings were ripped from her ears and her hair was
pulled out.

"They could hear her screaming and observe the beatings,"
Piasecki said. "Sometimes (Lovell) would go to the children's
rooms and hide underneath their bed. They'd see their father enter
the room and drag her out from under the bed.

In a telephone interview Friday, Joseph Biela told The
Associated Press that the testimony was filled with "lies."

"Everything was fine," said Joseph Biela, 61, who said he is
confined to a wheelchair or a walker.

"I beat my wife but never my kids," he said.

Asked whether the beatings were severe, he said, "That you will
have to ask her."

"I guess some of them were, I don't know. I'm the one paying
for it now ... She was my best friend and I didn't know it at the
time."

Jeff Biela, James' older brother who recently graduated from law
school, said their dad would "bind or handcuff" their mom and
whip her "pretty much nightly" in the bedroom next to theirs.

"It was a tortuous beating. I can still hear it in my mind, the
whipping noise the belt would make as he would whip her and her
begging him to stop," Jeff Biela said.

Biela's sisters would hold hands and sing to each other to drown
out their mother's screams, according to Kim Eastman, an older
sister. She remembered she feared leaving their bedroom in the
evening, even to go to the bathroom.

"We would keep buckets under my bed," Eastman said.

Lovell, who now lives in Spokane, Wash., testified late Friday
that her husband would strike her if she failed to bring home his
beer or cigarettes.

But often "there was no rhyme or reason," she said, adding
that he sometimes used automobile fan belts to tie her to the
bedpost before beating her. She didn't tell anyone because she was
"ashamed."

Lovell finally separated from her husband after he nearly killed
her for showing up without the tequila he wanted after they moved
from Illinois to Reno in 1990.

"He pulled me by the hair and slammed my head on the floor. He
kept hitting my head on the floor - a cement floor with a carpet. I
thought I was going to die," she said.

Just then the police showed up and arrested him because for the
first time the children had fled to their aunt's house a mile away
and she called 911.

Deputy District Attorney Elliott Sattler said that while the
experiences described in court must have been horrible, none of the
siblings grew up to become a violent criminal.

Although the U.S. Marines court-martialed James Biela because he
was AWOL and tested positive for marijuana, he was an average or
better student through school, hard worker and provider for his
girlfriend and son prior to embarking on the string of sexual
assaults in the fall of 2007, Sattler said.

"All of the sudden he starts raping women, stealing their
underwear, breaking into homes, violating women in the most
despicable ways possible and choking women to death. How do you
explain that?" he asked Piasecki.

"I can't explain that," she answered.

"How is it 16 years removed from this horrible father he snaps
and starts raping and killing people?" he asked again.

She said her profession doesn't have a good understanding of how
early experiences affect people later in life. She said there
typically is more of an "association" between such events rather
than a "cause and effect."

Joseph Biela told AP on Friday he hopes his son's life is
spared.

"Let him spend the rest of his life in jail," he said. "If
they let him out, he might do that again."
