Arlington police are investigating the events that led up to a man's shooting death Thursday night.
Authorities say around 9:30 p.m. officers responded to a shooting at an apartment near 1000 block of South Center Street.
Police say when they arrived, they found 19-year-old Aaron Padilla near an apartment doorway who had been shot. He was pronounced dead at the scene.
Detectives believe there were multiple people at the location prior to the shooting and that Padilla may have been involved in "high-risk activity."
Investigators are now working with the apartment complex to obtain video surveillance and are searching for possible witnesses.
Investigators have not ruled out the possibility that robbery may have been a motive in the shooting, according to authorities.
