Rachel Nicole Pittman, a Redwater, Texas, teen who pleaded guilty last month to the 2011 murders of a mother and her two young children, planned and carefully concealed her crimes.

Pittman, 18, secreted a four- to five-inch, wooden-handled kitchen knife in the waistband of her shorts and carried a two liter soda bottle filled with gasoline with her when she walked a short distance from her home on Farm to Market Road 991 to the house where Amanda Doss, 34, lived with her two children, Guinevere Doss, 11, and Texas Johnson, 8, according to Bowie County Sheriff's Office reports used to create the following account.
