McKINNEY - A company put up a $10,000 reward Monday to help solve the slaying of a house saleswoman killed over the weekend in McKinney.
Schepps Dairy announced the reward as investigators continued to search for clues in the fatal stabbing of 40-year-old Sarah Anne Walker, who was found dead Saturday in a model home at The Hemingway at Craig Ranch community.
Police are investigating several theories, including the possibility that Ms. Walker knew her attackers, McKinney police spokesman Capt. Randy Roland said. Walker was stabbed 27 times on her upper body.
"Police experience shows that [being stabbed] 27 times is a very personal attack," Capt. Roland said Monday.
Collin County medical examiner William Rohr told police that a "sharp-edged instrument" was used in the attack, but investigators said they don't know exactly what kind of object was the murder weapon.
Walker also suffered bruises in the attack.
A couple on a house-hunting trip stumbled upon the crime scene about 1:30 p.m. Saturday. Furniture, plants and other items were strewn across the floor. Many of Walker's wounds were defensive, indicating that she put up a fight.
The attack stunned residents of McKinney, many of whom moved to the growing Dallas suburb to avoid crime.
It is the second slaying of the year in McKinney.
Walker, who was recently divorced and had a 4-year-old son, was a saleswoman for D.R. Horton. The company did not respond Monday to requests for comment.
Walker's ex-husband, Randy Tate, did not return phone calls Monday, but he spoke highly of his ex-wife over the weekend. The couple divorced in November.
Jeff Domen, Walker's divorce attorney, said Monday that he was shocked to hear of her death.
"A lot of times when people go through a divorce, so often you see people at their worst," Domen said. "I never saw that with Sarah. She was always happy and always bubbly. She was always a pleasure to deal with."
Domen described Walker's divorce as amicable, saying she and Tate planned a birthday party together for their son, Josh, while they were in the middle of their divorce.
"She spoke the world of Josh and loved him and took care of him," Domen said.
Tate and others have said they don't believe Walker had any enemies. But her sister said Walker was attacked in her Frisco home last Thanksgiving. Frisco police said they have no record of the assault.
In another incident, Frisco police were called to her home Oct. 31 when she reported that a friend had stolen some property. When police arrived, there was nothing missing. Walker was apparently intoxicated and had a bump on her head, according to Frisco police.
McKinney police have not named any suspects in the case.
Ed Spencer of Schepps Dairy said Monday that the company hopes that the $10,000 reward will encourage people to come forward with tips. The money will be paid for information leading to an arrest and indictment. The offer will be good for six months.
Spencer said the company has distributed $350,000 for rewards in criminal cases across North Texas. Rewards are paid in about 25 percent of cases, he said.
"All murders are tragic, of course, but some committed against elderly, the very young and everyday working people are particularly compelling," Spencer said. "It's just to try to help the McKinney Police Department solve the crime."
