SAN ANTONIO -- Two suspects are in custody Monday after a robbery in a San Antonio shopping mall ended in a shooting that left one man dead and several other people injured, police said.

Police Chief William McManus said the two suspects robbed a jewelry store at the Rolling Oaks Mall on Sunday afternoon. After the two men fled the store, a man described by McManus as a "good Samaritan" tried to stop them.

One of the robbers fatally shot the man, McManus said. A second individual, who was carrying a licensed concealed handgun, then shot and wounded one robber.

The second suspect, who initially fled the scene, was apprehended Sunday night after a car crash in nearby Converse, police said in a statement early Monday. Two weapons were recovered from the suspect.

McManus called the fatal shooting "absolutely senseless." The victim's name was not immediately released by authorities.

The second robber fired his weapon as he fled the mall, injuring a man and a woman. They, along with the wounded robber, were taken to a hospital, said San Antonio Fire Chief Charles Hood.

Two other people -- a woman who complained of chest pains and a pregnant woman who had labour pains -- were also taken to hospitals, Hood said.

Authorities have released no details on the conditions of the injured bystanders, but police said the wounded suspect was in critical condition.

Authorities said both suspects face preliminary charges of capital murder and aggravated assault with a deadly weapon. Police have not released the names of the suspects.
