Horrified patients and family members watched as a man stabbed the nurse in the chest . `` She was just saying ... ' I 'm hurt . He got me , ' '' witness Jana Jackson told CNN affiliate KLTV . `` And that 's when we realized there was blood all on the front of her scrubs . '' Hours later , authorities pronounced Sandidge dead . Police said four others were wounded when 22-year-old suspect Kyron Templeton attacked visitors and employees Tuesday morning at Good Shepherd Ambulatory Surgical Center in Longview , Texas . The hospital 's president told reporters that the dedicated nurse died trying to save her patients . `` Nurses are protectors by nature . And Gail , she fit that profile , '' said Steve Altmiller , head of Good Shepherd Health Systems . `` She was protecting her patients in an act of courage today , and in so doing , she lost her life . '' He described Sandidge as `` a seamstress , a Sunday-school teacher of 2-year-olds , a huge Baylor fan , a mother , a grandmother , a healer , a trainer , a mentor , a nurturer .

He was arraigned on one count of first-degree murder and four counts of aggravated assault with a deadly weapon Tuesday . But authorities have n't identified a motive , a police spokeswoman said . Witnesses told KLTV they saw a man running through the surgery center around 7 a.m. with a hunting knife , screaming , `` You 're not going to kill my mother . '' `` He had a death grip on the knife and he was just muttering and his eyes were kind of wild-looking , '' said Jackson 's husband , Chad . `` It was just , he was very confused . '' Moments later , the surgery center about 120 miles east of Dallas turned into a crime scene . Some staff members rushed patients into safe areas .

That 's why we go to church . They pray . They say their prayers every night . '' And now , he said , Sandidge and her family will be in their prayers . Man sees pregnant wife stabbed on videochat .
