The attorney for Minnesota Vikings quarterback Daunte Culpepper said Thursday that a crew member on a players’ boat cruise admitted he had engaged in sexual activity with a woman, and the attorney questioned why that boat company employee wasn’t charged while four Vikings on the cruise were.

Attorney Earl Gray (above) said he learned about the employee’s activities on the Lake Minnetonka boat when he read the case documents from Hennepin County Sheriff’s Office investigators.

“Mr. Culpepper is charged with an offense that can’t be proved and he will be found not guilty,” Gray said. “The only reason he was charged is because of his name.”

The employee is a male relative of the owners of Al & Alma’s Supper Club and Charter Cruises, which supplied two boats Oct. 6 for the annual party thrown by first-year players for their team, according to multiple sources with knowledge of the case. None of the sources identified the employee by name, and the charging documents in the case do not name any of the crew members.

The employee touched the woman sexually during a lap dance, sources said.

Gray said Culpepper is obviously upset about the charges. He’s not worried about whether his client would have to “finger teammates” if he goes to trial.

“Not in a case such as Daunte’s. The case is so thin. I haven’t crossed that bridge yet,” Gray said. “Usually the state has the burden of proof beyond a reasonable doubt.”
