She said her son went by the name "Pea." "Someone dared to shoot him -- they dared to shoot my child," Ramey-Trimmer said. "My precious child ... for a gun, or a girl, or for whatever reason they shot him." Ramey-Trimmer told 8News that Pea was a sweet person and caring to everyone, whether they be family, a friend or a stranger. 29-year-old Shamar "Pea" Trimmer.

He then picked up his mother and they headed to the hospital. "They said, 'I got bad news' and I said, 'He's not dead ... he can't be dead, he can't be dead' -- but he was dead," Ramey-Trimmer said, in tears. "I should have protected my child. I should have said, 'Don't go to the city. You don't have any business in the city.'" Ramey-Trimmer already had two biological children of her own before adopting the twins. She told 8News that Pea and Gemar were both were god-given. "He [God] gave me Gemar and Shamar," she said. "It was a perfect fit for me and I love having them as my family. They are my family and they always will be my family." ...read more read less
