A 23-year-old man is home from the hospital after a shooting left him wounded and killed his sister, Joyce Cassandra Medina. KENS 5 spoke with Medina's family on Wednesday.

Kelly Sandoval, Medina's sister-in-law, said that the family still has a lot of questions.

"She was loving, hardworking, and she never did anything wrong," Sandoval said. "She always had this beautiful smile."

Police said that the shooting happened quickly. Someone knocked at their door and opened fire. Witnesses reported seeing a red dodge pickup truck leave the scene. As of Wednesday, there were no suspects in the case.

"It just doesn't make sense. That's why a lot of us are still wondering why," Sandoval said.

Joyce would have graduated from Texas A&M-San Antonio this year. She was on her way to becoming a teacher. She was also a true San Antonian and shared her immense love for the Spurs.

"Ever since she was a little girl, it was a big jersey and little Cassandra," Sandoval recalled. "To just recently, she was just at the game this past weekend."

A GoFundMe page for Joyce's Memorial Fund has been set up to assist her family with medical and funeral expenses.
