ORANGE COUNTY, Fla. -- A husband is free of accusations he murdered his wife, a popular Orange County teacher. Prosecutors believed Alwynn Walker had stalked his wife right up until he killed her. Andrea Walker was found murdered near her car in June 2007.

As soon as the verdict came back, there was an emotional outburst from the defendant's family. They cried and hugged each other. On the victim's side, loved ones were stoned faced and immediately left the court.

Alwynn Walker is a free man. After being accused of stalking and killing his estranged wife, a jury found him not guilty.

"I knew my brother did not do it, regardless of the situation of their marriage, he's a good man," the suspect's sister said.

Walker was charged with first-degree murder, accused of killing Pine Hills Elementary School teacher Andrea Walker. Prosecutors said the two were in the middle of getting a divorce and Walker wanted insurance money.

Detectives accused Walker of using GPS and Internet software to spy on and stalk his soon to-be-ex wife. But the defense said prosecutors never proved murder. They said investigators were on a witch-hunt and refused to look into other possible suspects, such as the victim's other romantic interests she had been seeing on the side.

After deliberating for two and half hours, the jury agreed.

Walker had his head on the desk for several minutes after the verdict, too emotional to even get up. He walked out of the court and vowed to re-start his life.
