A North Carolina jury found former NASCAR driver Greg Biffle invaded his then-wife's privacy, in a civil trial that concluded Monday.

According to WSOC TV in Charlotte, the jury determined that Biffle did “intrude offensively upon the privacy” of his then-wife, Nicole, by installing cameras in their bedroom and bathroom.

However, the jury awarded Nicole Biffle only $1 in damages, and answered "No" on all other claims against the former driver. The plaintiff had sought $9 million in damages.

“What the jury said sends a loud message that they don’t believe there was wrong doing,” Biffle said (via WSOC).

According to court documents, Biffle used the cameras to discover Nicole Biffle was having an affair. Biffle and his wife divorced in 2015.

During 12 days of testimony in the trial, Biffle denied doing anything inappropriate, and said his wife had been aware the cameras were there. He has sued the man she was having an affair with for alienation of affection for ending his marriage.

Nicole Biffle's attorney claims the verdict proved the former driver did something wrong. A hearing to consider the issue of punitive damages is set for Monday.

The 48-year-old Biffle drove from 2002 through 2016 in NASCAR's Cup series, earning 19 victories and finishing in the top 10 in the series six times. He's now an analyst on NBC's show "NASCAR America."
