Stubblefield got snagged in the BALCO case for lying to federal investigators about his steroid use. If proven to be true, these new accusations could send him to prison as a violation of his probation.
Stubblefield was a defensive star for the 49ers. After helping the team win a Super Bowl and becoming the NFL's defensive player of the year, he scored a six-year, $36 million contract with the Washington Redskins, and landed a role in a Hollywood film opposite Ben Affleck.
He finished his career back in the Bay Area with the Niners and Raiders, and settled in San Jose. His retirement has been anything but quiet.
"I'm very scared of this guy," said Stubblefield's former fiancée Melanie Wade. "That's my main reason for coming to you guys and writing that letter."
Twenty-six-year-old Wade contacted the I-Team because she is worried the authorities are not doing enough to protect her from Stubblefield. After a tumultuous three years together, Wade broke up with him last month, four days before their wedding. She says she tried to leave several times.
"He would lock me in and not let me leave the house, and tell me threats, like 'I'm not done with you 'til you're six feet under,' like 'I'm the only man you're going to be with,'" she said.
Wade says the relationship began to unravel after Stubblefield admitted lying about his steroid use to federal investigators in the BALCO case. Stubblefield received a reduced sentence of two years probation and a $5,000 fine because he cooperated with investigators, "providing the names of players, trainers, and others associated with the NFL who may be involved in on-going activities with illegal drugs in professional football."
At his sentencing in February, Wade was by his side.
"It was hard for him, he was depressed about it," she said. "It was hard for him to leave his house when he had to admit that."
It also was apparently hard for Stubblefield when Wade left him for good. In her application for a restraining order that was approved by a Santa Clara County famiily court judge in August, Wade says Stubblefield would call 50 times a day or more, sometimes leaving long, rambling messages.
"I know you're an angel," said Stubblefield in a phone message. "And I know you're here for me in my life for a good reason."
In court documents, Wade describes a dangerous confrontation.
"He was running me off the road, it was almost like a horror movie," she said.
Wade left her work as a personal trainer at about 11 p.m. one night last year, and Stubblefield was waiting for her.
"I was on my bicycle and I told him to leave, leave me alone, and he was really irate, he wasn't leaving, so he followed me home," she said.
She turned down a darkened road trying to escape, but Stubblefield followed in his jacked-up Chevy Suburban.
"And he bumped me off my bike and I went forward and I got cut up and bruises and got back on my bike and continued to go home," she recalled.
When she finally got back to her apartment, Wade says Stubblefield was already there.
"And so I got this big rock and threw it at the truck and I ran into my apartment," she said. "And he just waited out there like a shark in the water."
"And then there was a big pounding on the door," said Melanie Wade's mother, Kellie Wade, who told San Jose police she personally witnessed the threats when Stubblefield came looking for her daughter one night three months ago. "And I told him she wasn't there, and he said he has someone that's going to go after Melanie and for Melanie to watch her back."
The I-Team called Stubblefield several times for comment. At one point, he said he would speak with his attorney and call back, but didn't.
So we caught up to him at Kezar Stadium a week ago where he was coaching the varsity defense for San Jose's Valley Christian High School. We were careful not to raise these sensitive issues in front of his players. He told us he wouldn't talk to us before a high school football game. Later, he told us to speak with his criminal defense attorney Dan Nicholson.
Nicholson did not return our calls for an interview, but yesterday he sent an e-mail saying, "We deny the allegations contained in the restraining order request, but in the interests of privacy and closure, we decline to make a statement."
Stubblefield and his lawyer have not addressed another serious accusation contained in a police report and noted in Wade's journal.
"It's a listing of like the day I went to the post office and saw that my mail was being stolen, and the day of the police report of the forgery and the stolen mail," said Wade.
Wade says Stubblefield went to the post office, forged her signature on a change of address form, and had her mail forwarded to his house, including her paychecks, phone bills and bank statements.
"All of my accounts, every single one, he went online and he logged in like it's me and he created passwords," she said. "So I couldn't even get into my accounts online."
"If you're changing someone else's mailing address to come to your house, and they haven't approved it and that's not their mailing address, then you're submitting a false document to postal officials," said ABC7 legal analyst Dean Johnson. "It's potentially a federal crime."
The I-Team has confirmed that U.S. Postal Service investigators are looking into Wade's complaint.
Wade remains afraid for herself, but also for the students Stubblefield comes in contact with at Valley Christian High School, both male and female.
"And I feel like those kids are at risk because they spend so much time with this animal," she said. "I really feel like he's an animal. I mean he just, he loses it. He has no sense of right and wrong. He rages, he sees red."
Asked what she wants to now, she said, "Just peace and quiet. I just want to be left alone. I just want this all to be over with."
Wade is getting help from the Crime Victims Program to relocate to a new home where she hopes Stubblefield can't find her. They are both scheduled to appear in family court next week as Wade tries to extend the restraining order to five years.
The other question -- Valley Christian High School stood behind Stubblefield during his problems with BALCO. We'll see how they respond to this latest controversy.
