Los Angeles city officials announced on Wednesday they were offering $50,000 in rewards to help close two homicides.
Police were looking for the people responsible for the stabbing of Roshon Davis, 26, and the shooting of Nelva Hernandez, 44. Both were killed earlier this year in separate incidents.
"I just want someone to help find the person who did this to him so I can have peace of mind," said Gwendolyn Porchia, Davis' mother.

Davis, a father of four young daughters, was killed by an unidentified male while waiting at a bus stop on the corner of South La Brea Avenue and Coliseum Street on Jan. 29, authorities said.
He was found calling out for help in an alley behind his apartment complex, police said.
Two months later, Hernandez was killed when a bulltet struck her in the head while she was sitting in front of her family's home in Exposition Park, authorities said.
