Crystal Jackson, 24, was a mother to a five-year-old girl. Her sister broke down in tears while speaking to us about Jackson. She said Jackson was a nice person and loved her girlfriend, 24-year-old Britney Cosby. The two had been together for two years. Cosby's family members also are still visibly upset after finding out that the couple were found dead in Port Bolivar. Their bodies were found Friday morning next to a convenience store dumpster. Jackson's father says he last heard from his daughter on Wednesday. He said she worked as a security guard, while Cosby was a barista at Starbucks. Both lived at Cosby's great grandmother's home.... Relatives say the two women went to Galveston for Mardi Gras. Authorities say they were killed in different ways, and it's possible the suspects murdered them elsewhere and moved their bodies.

The police have released a sketch of the suspect.
