There is new information in the case of a man gunned down in front of a political candidate meeting voters in Philadelphia. Police say the victim’s friend was murdered just a few hours later. NBC10’s Monique Braxton is in East Mt. Airy with the details. (Published Monday, April 25, 2016) 
  
 Two friends were killed in two related shootings a short distance away and just hours apart -- one of which was witnessed by a Pennsylvania House candidate who spoke with the victim only moments before his death Sunday. 
  
 Chris Rabb, a Democratic candidate running for state representative of Pennsylvania’s 200th legislative district, was canvassing on the 1400 block of Vernon Road in Philadelphia around 3:30 p.m. Rabb's campaign manager told NBC10 the candidate introduced himself to a 21-year-old man who was in the area and they had a conversation. 
  
 The man, later identified as Alex Cherry, told Rabb he wanted to work the polls during Pennsylvania's primary Tuesday and was interested in his platform, according to the campaign manager. A volunteer with Rabb then took down Cherry's number. As Rabb and his volunteer walked away a gunman suddenly walked up to Cherry and shot him in the head at point-blank range, according to police. The gunman -- described as a man standing around 6-feet tall with short hair -- then returned to shoot Cherry two more times, said police. 
  
 "I asked my colleague to get his information," Rabb said. "And moments after we got his information he was shot in the head. I don't wish that on anyone." 
  
 Rabb managed to pull his volunteer to safety into a nearby store. Cherry was pronounced dead at the scene at 3:43 p.m. Gunman Kills Man in Front of Pa. House Candidate 
  
 Police are investigating two related shootings, one of which occurred in front of a Pennsylvania House candidate in Philadelphia. NBC10's Aundrea Cline-Thomas has the details. (Published Monday, April 25, 2016) 
  
 "I seen all the police cars but I had no idea that it was someone in my family," said Vyvyan Harris, Cherry's aunt. "But then my nephew walks over to me and says, 'Aunt Viv. He's gone.'" 
  
 Neither Rabb nor his volunteer were injured. Police also say they were not the gunman's intended targets. The campaign manager told NBC10 Rabb was "beyond devastated" by the shooting. Rabb was later interviewed by homicide detectives. 
  
 The gunman was last seen fleeing on foot southbound on the 7900 block of Fayette Street. Police have not released a detailed physical description of the suspect but say he was wearing a light grey hooded sweatshirt. 
  
 A few hours later around 7:30 p.m., about a block away on the 8000 block of Temple Road, Cherry's friend, 18-year-old Elijah Frazier, was struck and killed in a shooting. A gunman started shooting at a crowd of people after getting out of a red sport utility vehicle, investigators said. 
  
 A bullet struck Frazier in the back while a 17-year-old boy was grazed in the head. Surveillance video captured Frazier stumbling into a nearby Chinese take-out and then collapsing to the ground. He was rushed to Einstein Hospital where he later died from his injuries. The 17-year-old is expected to recover. 
  
 Frazier and Cherry were friends, a police source with knowledge of the investigation told NBC10's Monique Braxton. Investigators looked at the Somerville Gang, which has been feuding with the Vernon Road Gang, as possibly being behind the shootings, said the source. 
  
 "I'm very frustrated by the fact that we were not able to prevent this second homicide," said Philadelphia Police commissioner Richard Ross, who believes the shootings are gang-related. "We do believe that these are two rival factions. What they're fighting over we haven't pinned that down right now." 
  
 Police didn't immediately make any arrests in either shooting. 
  
 Rabb later released a statement on the deadly shooting: ||||| PHILADELPHIA (AP) — An 18-year-old man was shot and killed in Philadelphia in what appeared to be retaliation for the death of a 21-year-old man who was shot while talking to a candidate for the Pennsylvania House, police said. 
  
 Officials said a man was shot in the head Sunday afternoon while speaking to Democratic candidate Chris Rabb and a campaign volunteer about the state's upcoming primary. 
  
 "He was enthusiastic about the political process," said Rabb, who is running for a seat in the 200th District. 
  
 The man told Rabb that he was planning to work at his local polling place on Tuesday. 
  
 "This impressed us and we were in the process of encouraging him to join our campaign," Rabb said late Sunday in a statement. "Moments after he gave us his contact information he was murdered." 
  
 Police say the man was shot twice in the head, and was pronounced dead at the scene. Rabb was able to pull his volunteer to safety in a nearby convenience store. They were not injured. 
  
 A few hours later in the same neighborhood, police said an 18-year-old man was shot in the back and a 17-year-old boy was grazed by a bullet in a drive-by shooting. The 18-year-old was taken to a hospital, where he later died. The 17-year-old was expected to recover. 
  
 Police did not immediately release the names of the victims. 
  
 "We do believe this is retaliation," said Commissioner Richard Ross. 
  
 He said police would patrol the neighborhood to try to prevent more violence. 
  
 "We're going to continue to do what we do and hopefully try to save lives," he said. |||||
