The family of an Iraq war veteran wants to know why he ended up dead after being subdued with pepper spray by guards in a Dallas County jail complex.

Autopsy results are pending on 32-year-old Gregory Kitchen, who died in January.

The Dallas Morning News reported Friday that relatives of another man, who died in June 2008, are also questioning guard restraint methods and have sued. Corey Bailey was 31.

A report indicates Bailey, held on a drunken-driving charge, died while guards were moving him for a mental health evaluation. The autopsy report says Bailey died of toxic effects of the drug PCP, including excited delirium, in combination with "restraint by police officers."

Army Sgt. Denise Kitchen awaits results of her husband's autopsy. He was jailed on a felony burglary charge.

A sheriff's department spokeswoman declined comment.
