Police sought help from the public Saturday as the search for a Wisconsin man wanted in the deaths of his two young daughters and their mothers stretched into its third day.

Authorities released no new details on the slayings but continued to call 38-year-old Tyrone Adair armed and dangerous. He has strong family ties to the Madison area, but so far has eluded capture. Police have warned law enforcement agencies nationwide to watch for him.

"We're just encouraging anyone who has any information at all to come forward," Madison Police Lt. Wayne Strong said.

Prosecutors charged Adair, of suburban Middleton, on Friday with two counts of first-degree intentional homicide in the deaths of 33-year-old Tracy Judd and 23-month-old Deja Adair, Judd and Adair's daughter.

They also consider him a "person of interest" in the killings of 25-year-old Amber Weigel and 2-year-old Neveah Weigel-Adair, Weigel and Adair's daughter.

His family issued a statement through police late Saturday evening pleading with Adair to surrender "immediately."

"Before anyone else is hurt please turn yourself in," the statement said.

Dorothy Carter, Adair's grandmother, told The Associated Press on Saturday he lost his job at Clack Corporation, a water-treatment component manufacturer in Windsor.

"He's always been a good guy," Carter said, fighting back tears. "He likes to prepare Christmas for his kids ... for him to be out of work this time of year and not have any money at all ... and he's not the type of kid who would ask for anything. I know it wasn't right what he did.

"He was depressed. I know that's no excuse, but that's what happened."

Two Clack employees who would not give their names declined comment on Adair's status with the company when The Associated Press contacted the company Friday. Peter Chermak, the company's vice president and CEO, told the Wisconsin State Journal for Saturday's editions that Adair hadn't worked there for six months.

Chermak didn't immediately return a message left at his office Saturday and no home listing for him could be found.

Court records show Adair has convictions for battery and bail jumping. A woman took out a restraining order on him in 2006, alleging he stalked her, slashed her tires and destroyed her computer, phone, television and bed.

He also was involved in paternity cases with both Judd and Weigel over his children.

Court records indicated Judd was a stay-at-home mother.

Jason Graser, Judd's ex-husband, declined comment Saturday. Jackie Scott, co-owner of Scott's Pastry Shop in Middleton, said Judd worked there about eight years ago. She said Judd was outgoing and well-liked.
