INDIANAPOLIS -- A police officer died after being shot multiple times while responding to a traffic crash on the south side of Indianapolis, authorities said Thursday. 
 
 During a press conference, Southport Police Chief Thomas Vaughn identified the slain officer as Lt. Aaron Allan was a 6-year veteran with the department and he had nearly 20 years of law enforcement experience, CBS affiliate WTTV reports. He is survived by his wife and children. 
 
 Sgt. Kendale Adams of the Indianapolis Metropolitan Police Department says Allan was responding to a crash where someone was trapped Thursday afternoon when he was shot. He says Allan died at Eskenazi Hospital. 
 
 Adams says two other officers at the scene returned fire, striking a person inside the vehicle. He says that person and a second person injured in the crash were hospitalized and in custody with non-life-threatening injuries. 
 
 "Lt. Allan was a hard worker and today was no different. He responded to a crash with urgency to preserve life and tragically his was lost," said Chief Vaugh at the press conference. "We appreciate the community support as we continue to work through the loss of our brother." 
 
 A veteran on the scene said the incident is "disgusting" and makes him question his family's safety, WTTV writes. 
 
 "It's just disgusting you know. Being a vet, I was in the service, we're kind of all in the brotherhood. We're not going to be able to walk our kids down the street because of some foolishness like this," said David Andrzeejewski. "I mean, he pulled over a kid, he probably woke up in the morning told his kids goodbye gave them a kiss, pulls a car over. Next thing you know he's in the hospital fighting for his life. It's horrible. What's it coming to? When's it gonna end?" 
 
 WTTV reports that Indianapolis Mayor Joe Hogsett released the following statement regarding Lt. Allan's death saying the incident was "tragic" and "shocking." 
 
 "Today, Lieutenant Aaron Allan was doing what officers do each day: responding to the scene of an accident ready to help someone in their time of need. His death is a shocking and tragic reminder of the difficult, often dangerous work of police officers across Marion County. Together, our community grieves for the Allan family and for all the men and women who risk their lives on a daily basis to protect our city and its citizens." 
 
 Southport is an enclave within the city limits of Indianapolis. ||||| SOUTHPORT, Ind. -- A Southport police lieutenant was killed Thursday afternoon in a bizarre shooting while responding to help victims of a crash on Marion County's south side.

 A witness at the scene said the driver was upside down in the vehicle when he began firing at Lt. Allan. That witness described hearing "at least 20" shots fired. 
 
 Lt. Allan was rushed to Eskenazi Hospital where he later died. He was a six-year veteran of the Southport Police Department. 
 
 The responding Homecroft police officer along with an off-duty Johnson County deputy returned fire, striking the suspect, according to Sgt. Adams.

 Brown remained hospitalized Friday in good condition, Indianapolis Metropolitan Police Sgt. Kendale Adams said. 
 
 Allan, 38, was responding to a traffic accident involving a car that had flipped over on Madison Avenue, a few blocks north of Southport Road. 
 
 As Allan approached, one of the occupants of the car started shooting. Whether the shooter was inside the car was unclear. A Homecroft Police officer and an off-duty Johnson County deputy had also stopped to help. They shot back, wounding the suspect, police said.

 The deputy was off duty, in civilian clothes, drove his personal vehicle and fired his personal handgun, Cox said. 
 
 The officer has a background in nursing. He saw the crash and stopped. He was trying to assist the victims before the suspect started shooting, Cox said. 
 
 Cox did not identify the deputy. The deputy will not be giving public statements, Cox said.

 “The Indianapolis Policing community is simply heartbroken by the tragic loss of Lieutenant Aaron Allan. 
 
 "Lt. Allan leaves a loving family, friends and his sisters and brothers of the Southport PD and the entire Indianapolis police community. 
 
 "Aaron made the ultimate sacrifice while actively trying to render help to his fellow man in need. There is no greater sacrifice and our entire community is now absorbing the impact of such a tragic event.” 
 
 The FOP offered its support to Allan's family and his "extended law enforcement family."

 After the shooting, dozens of police cars lined the streets of the neighborhood. 
 
 A mangled wrought-iron fence and the toppled black car were the only blemishes in the otherwise well-kept lawns that stretched down Madison Avenue. 
 
 As dark clouds rolled in, the red, white and blue police lights danced across the windows of a home where an American flag with a thin, blue line rustled in the breeze. Across the street, investigators sifted through ankle-high grass, leaving a trail of evidence markers in their wake. 
 
 For hours, neighbors gathered in clusters along the crime scene tape, swapping theories about what might have happened before the shots were fired. What they knew for certain: It was unlike anything they had seen in their quiet, close-knit community. 
 
 Tina Tom said she was shocked when a neighbor knocked on her door and said an officer had been shot in the street. 
 
 “It was alarming,” she said. "I had goosebumps all over my face and my whole body.” 
 
 Betty Strohm, who once lived in the home where the overturned car landed, said several police officers live in the immediate area. 
 
 “This is a great neighborhood,” Strohm said. “Everybody watches out for everybody here.” 
 
 She called the shooting “devastating.” 
 
 “This never should happen to any police officer, especially when they’re giving their time to help our community,” Strohm said, her voice straining. “This is very, very sad.”

 At Eskenazi Hospital, officers and detectives were coming in and out. One person passing by told police, "Sorry about your comrade." 
 
 The Southport Police Department is a force of about 40 officers who are unpaid volunteers. The police chief is a paid position. Allan was working in a full-time paid position that began at the beginning of this year. 
 
 Allan had been with the department since 2011, according to a October 2015 article from the Southside Times. 
 
 He became the department’s first officer of the year in 2015 after being promoted to the head of Southport’s training division. When presenting the award to Allan, Vaughn highlighted a moment in August 2015 when Allan performed CPR on a man and saved his life. 
 
 Allan also had worked as a police officer for the Franklin Township Schools, a position he left in January, when he joined the Southport Police Department full-time, Chief Vaughn said. 
 
 Allen told the Southside Times that had he wanted to be a police officer since he was 5 years old. 
 
 At a news conference Thursday night, Vaughn remembered Allan as a dedicated public servant with a kind heart, fitting of his nickname: Teddy Bear. 
 
 "That’s because he tried to act real macho, but when a citizen or someone needed help, he was one of the first guys that was there," Vaughn said. "He didn’t always like that nickname, but it fit him." 
 
 Vaughn said the outpouring of support from community members and local and state police was encouraging. 
 
 "Without the support of our family, which is all police, it would be hard to get through this evening," he said. 
 
 Southport Mayor Russell McClure said at the news conference that he wasn't sure that Allan's loss had hit him yet. 
 
 "It comes as just a complete shock," McClure said. "It’s just a tragedy you just can’t imagine happening to your city, to one of your officers."

– A police officer was killed in Indianapolis Thursday by a crash victim he was trying to help, police say. Authorities say Lt. Aaron Allen was shot multiple times after approaching a car that had flipped in an accident on the city's south side Thursday afternoon, the Indianapolis Star reports. Another officer responding to the crash and an off-duty officer who was in the area returned fire, injuring the shooter, police say. Both people who were in the flipped vehicle were taken to a nearby hospital with non-life-threatening injuries and are now in police custody. Allen, 38, was pronounced dead at the same hospital. A witness tells RTV6 that the driver was trapped upside-down in the overturned vehicle when he opened fire for reasons that are still unclear. The witness says at least 20 shots were heard. Allen, the Indianapolis-area Southport Police Department's officer of the year in 2015, leaves a wife and children, CBS News reports. He had been in law enforcement for almost 20 years.
