ABILENE, Texas -

The court martial of a Dyess airman implicated in the Tiffany Klapheke case is set to begin Tuesday.

Senior Airman Christopher Perez was arrested last fall when 22-month old Tamryn Klapheke was found unresponsive in her home.

Perez was allegedly staying in the Klapheke home when the toddler died and her father was in deployment.

A military hearing last year revealed Perez was allegedly involved in an adulterous relationship with the toddler’s mother, 23-year-old Tiffany Klapheke.

Perez’s general court martial is set to begin Tuesday morning at Dyess Air Force Base. Tiffany is set to go to trial in January.
