GROSSE POINTE PARK, Mich. — A suburban Detroit man authorities describe as a "person of interest" in the strangulation death of his wife said Wednesday he will continue to cooperate with police investigating the slaying.

Bob Bashara refused to answer questions during a short meeting with reporters outside his Grosse Pointe Park home. He thanked supporters for the "love and respect" they have shown for his late wife, Jane Bashara.

"Both our families grieve and, in light of this horrific event, ask for your continued prayers, ask for your support and respect of our privacy as we deal with this heartbreak and try to cope," he said a day after his wife's funeral.

"This is an unconceivable tragedy. We have cooperated with law enforcement agencies and will continue to do so."

Bob Bashara, 54, has not been charged. He has been given a lie detector test.

The body of his 56-year-old wife was found a week ago in the rear seat of her luxury Mercedes-Benz sport utility vehicle in an east side Detroit alley, about six miles from the couple's home. Bob Bashara had reported her missing the night before.

Grosse Pointe Park Public Safety Director David Hiller did not immediately respond to calls for comment Wednesday from The Associated Press. The AP also left several messages Wednesday for Bob Bashara's attorney.

Jane Bashara worked as a marketing manager for an energy consulting company. She and Bob Bashara were married 26 years and had two adult children.

On Wednesday, their son, Robert, stood beside Bob Bashara and a woman Bashara identified as his mother, Nancy.

"My sister and I really support our dad and miss our mom so much," he told reporters.

Records show that the couple owned several residential properties on Detroit's east side and the Grosse Pointe Park area. Jane Bashara had a license in real estate sales, but it lapsed in 1991.

Their home in the exclusive community has a market value of $587,400, but is assessed at $293,700.
