An Oakland woman sits in jail this morning on suspicion of murdering her 2-year-old daughter. Tiffany Lopez, 19, who is three months pregnant and was arrested on child endangerment charges in December, is alleged to have suffocated "Kamilah in their second-floor apartment on the 2800 block of High Street." Initially telling investigators that she accidentally sat on her daughter, the Mary Jones-esuqe mom went on to tell police that "she had become frustrated with her daughter."

According to SF Chron, Kamilah was described as a "beautiful, intelligent, energetic - a lively baby" who loved the color pink and Dora the Explorer.
