BILLINGS - One of the 13 people killed by a gunman at Fort Hood in Texas was a physician's assistant with ties to Montana.

Michael Grant Cahill of Cameron, Texas, served in the Montana Army National Guard for many years and lived in Montana for 15 years.

His wife, Joleen, was born and raised in Roundup and she says they planned to retire there. She says some of the best times they had were at a family cabin near White Sulphur Springs.

Cahill, who was 62, worked at hospitals in Boulder and Great Falls and at the Veterans Affairs Clinic in Billings. He also served in the Montana Army National Guard with units in Havre, Helena and Bozeman from 1973 to 1987.

Joleen Cahill says the family hopes to hold an internment for her husband at a veterans' cemetery in Montana in May.

Authorities say Maj. Nidal Malik Hasan fired off more than 100 rounds Thursday at a soldier processing center at Fort Hood, killing 13 and wounding 29 before civilian police shot him.
