Updated at 2:03 p.m. Monday: Revised to include suspect's identity.

The man who was fatally shot while trying to stop a robbery at a San Antonio mall has been identified as 42-year-old Jonathan Murphy.

Authorities arrested two people in connection with the deadly robbery Sunday afternoon at the Rolling Oaks Mall in San Antonio.

San Antonio Police Chief William McManus said during a news conference that two men robbed the Kay Jewelers at the mall about 3:30 p.m.

Murphy, who was unarmed, attempted to stop the robbers from fleeing and was shot dead, McManus said. The chief called him a good Samaritan.

He had gone to the jewelry store with his wife, Aimee, to get their wedding rings cleaned, according to a GoFundMe page for his family.

"Jon loved Harleys, the Marine Corps, and being a good man, but over everything else I believe he loved his wife and family," Chris Cercone wrote.

Police said another man at the mall, who was legally carrying a concealed gun, shot and wounded the robber who killed Murphy.

The injured robber was taken to an area hospital and is in critical condition. His name has not been released.

The second robber ran off, firing his gun and injuring a man and woman, McManus said. He was arrested Sunday night and identified as 35-year-old Jason Matthew Prieto.

The two victims were hospitalized with injuries not believed to be life-threatening.

Two other people, a woman who said she had chest pains and a pregnant woman who had labor pains, were also hospitalized.

Shortly after the incident, Prieto wrecked a stolen vehicle at Loop 1604 and Coppergate in Converse, about nine miles southeast of the mall, police said.

Converse police later apprehended Prieto and he was turned over to San Antonio police, authorities said.

Two weapons were recovered, police said.

Both suspects face a capital murder charge and two counts of aggravated assault with a deadly weapon.

McManus described the incident as "a robbery gone really, really bad." He initially said six people were injured.

The mall in northeastern San Antonio was locked down and shoppers were told to take shelter where they were as authorities searched for the second robber. McManus said the people in the mall were safe and would be escorted outside.
