Relatives of 19-year-old Jorge Roman-Medina call his fatal shooting Sunday in Feltonville a mystery.
His mother and fraternal twin brother were visiting their native Puerto Rico, so no one was home when Roman-Medina was shot several times down the street from where he lived on the 4800 block of North Mascher Street.
Police reported no arrests Tuesday.
Roman-Medina was getting ready for his second year at Community College of Philadelphia, relatives said. He and his twin, Eugenio, had graduated from Community Academy of Philadelphia Charter School in 2011.
In 2009, he came to Philadelphia from Puerto Rico "to fulfill his life over here," said his sister, Maritza Fontanez, 32.
