CHARLOTTE, N.C. -- The wife of Jeremy Mayfield on Tuesday took out a restraining order against her husband's stepmother and principal witness for NASCAR's case against the suspended Sprint Cup driver.
Shana Mayfield filed the request at the Iredell County sheriff's department.
"She will be served as soon as they can find her," Shana told ESPN.com.
The order was sought three days after Lisa Mayfield showed up intoxicated at her stepson's home Saturday night and arrested on four counts of simple assault and for trespassing.
According to the arrest warrant, Lisa physically confronted the husband and wife caretakers living on the property, their daughter and her boyfriend. She is scheduled for trial on Sept. 14.
"[She] told our caretakers she would come back to kill us, she wasn't done," Shana said.
Lisa became a part of NASCAR's case to get her stepson's suspension reinstated after a federal judge granted a temporary injunction. She signed an affidavit saying she saw Jeremy use methamphetamines at least 30 times since 1998.
She also said Jeremy "cooked" his own methamphetamines until it became too difficult to obtain the ingredients.
Jeremy was suspended on May 9 after testing positive for methamphetamines during a random test taken eight days earlier. He tested positive again during a random test taken at his home after the suspension was lifted.
NASCAR presented the second test and Lisa's testimony in court documents to keep Jeremy off the track.
Jeremy argued that his stepmother's testimony was not trustworthy. He referred to her as a "whore" and accused her of killing his father, who according to police reports committed suicide in 2007. He also accused her of accepting money from NASCAR in exchange for her testimony.
Jeremy has been working for over a year on a wrongful death suit against Lisa and, according to Shana, plans to file soon. Lisa already has filed a civil suit against Jeremy for defamation of character.
Shana told a reporter from Charlotte television station WCNC that they were trying to keep the matter private with Lisa "and now with NASCAR's involvement our private matters have become public."
Jeremy has argued from the outset that he never took methamphetamine, that the positive test was the result of combining the prescription Adderall for Attention Deficit Hyperactivity Disorder with over-the-counter Claritin D for allergies.
Dr. David Black, who conducts NASCAR's drug testing program, has said that is not possible.
"Jeremy from day one has said what his stepmother was and I think Saturday night proved it," Shana told WCNC. "Hopefully, they [NASCAR] realize what they have in their credibility."
