The San Francisco Police Department has made an arrest in the fatal shooting of an emergency medical technician who was reportedly trying to break up a Mission Street altercation when he was killed.

As previously reported, 26-year-old Camilo Senchyna-Beltran was shot to death at 2 a.m. on Sunday, December 7 on Mission Street near 20th Street.

According to Mission Local, Senchyna-Beltran, a Mission District native, was celebrating a friend's birthday at nearby Bruno's nightclub when "a friend and an unidentified suspect got into an argument. Senchyna-Beltran stepped in to stop the fight. The suspect turned on him and fired one shot into his chest."

Senchyna-Beltran was pronounced dead at San Francisco General Hospital shortly thereafter.

Now SFPD are saying that the "unidentified suspect" is 21-year-old Taaron Bragg, who was arrested for "an unrelated robbery warrant and a misdemeanor theft warrant by Bayview Station officers" Sunday. Then they "recognized Bragg from a wanted homicide bulletin," SFPD said in their release, and "were able to develop information which identified Bragg as the suspect for the homicide."

According to the SFPD, "the motive for the shooting remains under investigation," but friends of the victim told Mission Local that it “was a random act — no one knew the person."

Senchyna-Beltran was raised in the Mission, and was living with his mother and grandmother in Bernal Heights at the time of his death. He was working as an EMT in the South Bay, and had been training to become a paramedic.

In their release, SFPD says that Bragg was arrested on suspicion of one count of murder and one count of attempted murder, in addition to the charges for which he was initially nabbed. He has been booked into San Francisco County Jail.

Meanwhile, a scholarship "to help a Mission neighborhood student study in the medical field" has been set up on the ScholarMatch website in Senchyna-Beltran's honor. Interested donors can contribute here.
