He ignored four phone calls from Linda Fisher, according to the affidavits, despite having checked his messages to retrieve them, before being notified of his wife's death later that evening.
The police affidavits said Jason Young was uncooperative from the beginning of the investigation and, when asked to come to the Wake County Sheriff's Office on the night of Nov. 3, 2006, did not inquire about his daughter's well-being or the cause of his wife's death.
The affidavits also included an e-mail exchange Jason Young had with one of his sisters after Michelle Young's death.
In referring to Cassidy, Kim Young wrote, "What happens when her little friends aren't allowed to come play with her or spend the night because rumor is her daddy killed her mommy?"
Jason Young wrote back: "You spend your days on the internet going into chatrooms where you're not going to find anything good written about the situation, but in time things will die down. Most people out there don't know one thing about any of this."
As of Nov. 6, 2008, Jason Young, according to the affidavit, has not been interviewed by police despite numerous requests in person and through his attorney.
Messages left with Roger Smith Jr. of Raleigh, Jason Young's attorney, were not returned and repeated attempts to reach Jason Young or his family were unsuccessful.
Jason Young is still living in North Carolina has custody of Cassidy, according to Fisher's lawyer.
Jennifer Powers, Michelle Young's best friend since high school, declined to comment on Stephens' civil court ruling or Jason Young's possible involvement in his wife's murder, but said that "somebody needs to be punished for this crime."
The two friends met as cheerleaders at New York's Sayville High School. Even after Michelle Young's move to North Carolina and subsequent marriage the two remained in contact every day.
Powers, 31, said that when Michelle Young first met her future husband, "she was thrilled."
"He has this very happy-go-lucky attitude that she thought complimented her," Powers said.
And Jason Young, she remembered, introduced her best friend to activities she'd never tried before including hiking and camping. When Michelle Young brought her then-boyfriend back to New York to meet her friends and family, Powers said everyone else saw the good in Jason Young that Michelle Young had seen.
"He certainly fit in right away," she said.
Powers, now living in Hoboken, N.J., said she last saw her friend in late October 2006. Michelle Young had come up to New York on a business trip, hoping it would coincide with the birth of Powers' first child. When the baby didn't come as scheduled, Michelle Young postponed her trip home so she could be there for the birth.
Powers said her best friend was her daughter's first visitor. The two were looking forward to raising their babies together and Powers said she was anxious to hear all the parenting advice her best friend would have.
Now, she just misses the day-to-day friendship.
"I do hope charges will be brought against the person that did it," she said. "I think we need to see some justice."
