Details of Disappearance

Cowan was last seen at the residence she was building in Oak Forest RV Park in Austin, Texas on January 14, 2001. A trail of her blood was found at the home after she went missing.

In December 2005, nearly five years after Cowan disappeared, her son-in-law, Thomas James Negri, was indicted for her murder. Negri and Cowan had been business partners prior to her disappearance. He had been considered a person of interest in her case since shortly she went missing.

Prior to his arrest, he gave a media interview asserting his innocence; he stated Cowan owed him money and he believed she had left of her own volition. In July 2007, Negri was convicted of murder and sentenced to serve 20 years in prison and pay a $10,000 fine.

Cowan was depressed at the time she disappeared due to several recent deaths in her family. She was planning to retire and move from Travis County, Texas to her new home in Austin. Foul play is suspected in her case due to the circumstances involved.
