SAN ANTONIO -- Police are trying to figure out if a man who showed up at a hospital with a fatal gunshot wound is the same person who tried to hold up a convenience store.

Police said that two armed people who had their faces covered walked into Evans Ice House at 2908 Mission Road and demanded money from a clerk.

The clerk, though, didn't comply with the would-be robbers' demands and instead opened fire on them, police said.

A little later, a man showed up at Southeast Baptist Hospital with a gunshot wound to the chest.

He was then transferred to Wilford Hall Medical Center, where he died.

Some women who showed up with the man at the hospital were arrested and charged with aggravated robbery.

The clerk will not face charges since police considered his actions to be in self-defense.
