DETROIT -

Bob Bashara was 30 minutes early Friday when he arrived at the Michigan State Police post in Taylor to submit handwriting samples.

The Local 4 Defenders were there as Bashara went into the building with a retired FBI agent at his side. Bashara told the Local 4 Defenders that he always has, and will continue to, cooperate with authorities.

"Bob Bashara wants to find out who killed his wife, wants to find out what happened and the truth," Bashara said.

He said he's willingly given statements and taken a polygraph test.

Sources said investigators want samples from Bashara to compare it to several other pieces of evidence they're reviewing in the case, which include a check, a letter and a greeting card.

Three hours later, Bashara walked out of the police station.

"I did as they asked, completed the assignment. They were very cordial and I was very open and honest with them," he said.

Bashara attorney fought to be present

Attorney David Griem filed a motion with the Wayne County Circuit Court demanding to be present when the samples were given. But his request was denied by Wayne County Circut Court Judge Timothy Kenny.

"They had to go through a dog and pony show and it looks like today the dog lost and the pony won. Have a good day," Griem said.

Grosse Pointe Park mother found dead in January

Jane Bashara was found dead in the back of her SUV in a Detroit alley on Jan. 25. She had been reported missing the night before.

Sources say a man named Joe Gentz was forced to kill the Grosse Pointe Park mother under the order of her husband.

Gentz has been charged with first-degree murder and conspiracy to commit murder.

Bob Bashara has not been charged.
