 The wife of the suspect in an Arlington slaying says a revealing selfie set off an argument that ended with a fatal shooting Monday outside a drugstore. 
  
 Ricci Bradden, 22, is accused of injuring his wife and killing an armed good Samaritan. Bradden turned himself in at Department of Public Safety office in Hill County on Monday after talking with his Army supervisors and confessing to the shooting, police said. 
  
 Bradden was booked Tuesday afternoon into the Arlington City Jail, where his bail is set at $500,000. 
  
 Quinisha Johnson, who works at the Walgreens at 5600 New York Ave., told police she was surprised to see her husband there Monday because he was supposed to be at Fort Hood. 
  
 Johnson told WFAA-TV (Channel 8) that Bradden was upset about a photo that she had posted to Facebook that showed her cleavage. She said Bradden accused her of trying to get attention from other people. 
  
 “And I was trying to explain it to him, that I married you,” Johnson told WFAA. “You’re all the attention that I needed. And I could feel that he was getting mad, so I tried to walk off, and that’s when I heard him pull the gun out.” 
  
 Bradden fired a handgun twice, striking his wife’s ankle the second time, according to an arrest warrant. 
  
 Johnson told police she went into the Walgreens yelling for help. 
  
 Bradden ran to his truck after shooting at his wife’s feet, according to the arrest warrant. He told Army supervisors that a man ran up to him and told him to drop his gun. 
  
 Bradden confessed to slapping the gun out of the man’s hand and shooting him, according to the arrest warrant. 
  
 Officials identified the man who was killed as Anthony “T.J.” Antell Jr., 35. He owned the CrossFit Abattoir gym in Arlington, according to his Facebook page. 
  
 Antell had served as a Marine, KXAS-TV (NBC5) reported. 
  
 Antell, who had a concealed-carry permit, had grabbed a gun from his car and pointed it at Bradden’s car, said Arlington police spokesman Christopher Cook. Witnesses told police the gunman shot Antell in the head. 
  
 Police said Antell’s wife was with him at the drugstore when he was shot. 
  
 Bradden fled the scene and was headed south on Interstate 35, according to an arrest warrant. A relative took Bradden to a Department of Public Safety office near Hillsboro to turn himself in, police said. 
  
 Cook said it’s a subjective call as to what an armed person should do in this kind of situation.

 “Without having all the details, it would be inappropriate for me to speculate,” he said. 
  
 But Cook said police do not ask citizens to try to stop armed suspects. 
  
 “Any time that you can be the best witness you can be, we always recommend that,” he said. “Sometimes things turn out like this when you’re trying to stop a bad guy.” 
  
 Bradden faces a murder charge. Police said he will be taken from Hill County to Tarrant County after a court appearance. 
  
 A gym owner in Arlington has started a GoFundMe page to raise funds for Antell’s family. ||||| A former Marine who witnessed and tried to intervene during a domestic shooting Monday was fatally shot by an Army soldier accused in the initial altercation, Arlington police say.

An ex-Marine in Texas who witnessed a shooting in a Walgreens parking lot was shot dead as he tried to make a citizen's arrest, police say. The Arlington Police Department says Anthony Antell Jr., 35, went to his vehicle to get his gun after he saw Ricci Bradden shoot his wife in the ankle after an argument, the New York Daily News reports. "The good Samaritan tried to stop him, pointed his firearm at the suspect, told him to stop," Arlington police Lt. Chris Cook told reporters after the incident on Monday. "Suspect exited his vehicle and exchanged gunfire with the good Samaritan, killing unfortunately the good Samaritan." Police say Antell's wife witnessed her husband's death from their vehicle. NBC-DFW reports that the couple has three children. Bradden, a 22-year-old soldier, fled the scene but confessed the shooting to his Army supervisors, telling them he slapped the gun out of Antell's hand and shot him, reports the Dallas Morning News. Bradden, accompanied by a relative, surrendered to authorities later Monday and will be charged with murder. His wife—who ran into the Walgreens screaming for help after she was shot—is expected to survive. Cook told reporters that until all the details are known, it would be inappropriate to speculate on what an armed person should do in this kind of situation.
