MADISON, Wis. - Police yesterday found the body of a man wanted in two double homicides in Wisconsin in the car of one of his victims, a coroner said.

Tyrone Adair, 38, died of a gunshot wound, Dane County Coroner Raymond Wosepka said at a news conference in Madison.

Adair was charged Friday with killing Tracy Judd, 33, and 23-month-old Deja Adair, Judd and Adair's daughter. He also was wanted in the deaths of Amber Weigel, 25, and 2-year-old Naveah Weigel-Adair. All four bodies were found Thursday.

Yesterday morning, a land owner in Cottage Grove, a village of 1,000 people about 15 miles east of Madison, called police. He said he had found what turned out to be Judd's GMC Acadia outside a storage shed on his property.

Investigators found a revolver and a 9mm semiautomatic in the vehicle.

Detectives suspect that Adair killed Judd and Deja Adair on Thursday morning at the home they shared in the suburban town of Middleton, then went after Weigel and Weigel-Adair at their Madison duplex that evening, Dane County Sheriff David Mahoney and Madison Police Chief Noble Wray said.

According to a police timeline, a surveillance camera at the Branch Street Retreat bar, in Middleton, picked up Adair around 2 p.m. He remained at the bar for about 45 minutes, then took a cab back to Judd's house.

He left the house in the Acadia about 4 p.m. He then left a "somewhat remorseful" voicemail for his sister, Mahoney said. He would not say what the message said specifically.

A little after 6 p.m., Weigel's boyfriend found Weigel and her daughter shot in a car in their duplex's garage. Madison police asked Middleton police to find Adair's car.

About 9:15 p.m. officers found Adair's 2001 Chrysler 300M in a parking lot behind the Branch Street Retreat. Judd and Deja Adair's bodies were in the trunk. Wosepka, the coroner, said they were not shot but refused to say how they were killed.

Adair's motives remain murky. He had moved into Judd's home in December 2007, just before Deja Adair was born, but he was involved in paternity cases with both Judd and Weigel over their children. His grandmother has said that he lost his job this year.

Mahoney said that Judd was speaking to friends and relatives about breaking up with Adair.

Adair's motive for going after Weigel and her daughter remain unclear, Wray said. Nothing suggests any domestic violence between them, he said.

In 2006, a woman took out a restraining order against Adair, alleging he was stalking her and had destroyed her computer, phone and television after she decided to break up with him. That restraining order prohibited him from owning a firearm until 2010.

Wray said that detectives hadn't determined where Adair may have gotten the revolver, but it appears he purchased the handgun on Craigslist in August.
