Riley Ann Sawyers (March 11, 2005 – July 24, 2007) was a two-year-old American girl who was beaten to death by her mother Kimberly Dawn Trenor and her mother's partner Royce Zeigler in a filicide. Her body was later found in Galveston Bay, Texas. The level of decomposition meant that police were unable to immediately identify the remains and began a nationwide effort to learn the child's name. Riley Ann's identity was confirmed when her paternal grandmother, Sheryl Sawyers, notified police after seeing a composite sketch. Her remains were then positively identified through DNA testing on November 30, 2007. Prior to her 2007 identification, Riley Ann Sawyers was known as Baby Grace due to her age and sex. Home environment Riley Ann was the daughter of Robert Thomas Sawyers and Kimberly Dawn Trenor. Her mother became pregnant at the age of 15 when the pair developed a relationship while students at Mentor High School. Her father dropped out of high school during his junior year. The family lived in Mentor, Ohio, with Robert's mother, Sheryl, who was Riley Ann's primary caregiver. During this time, Riley Ann's parents grew apart and were no longer a couple. They all continued to live in the same home. Riley Ann's father began dating a woman named Catherine Priester, whom he later married. In October 2006, alleging physical abuse and having filed a domestic violence charge against Trenor, Sawyers left the home. In May 2007, Trenor and Riley Ann moved to Spring, Texas. Trenor married Royce Clyde Zeigler, Jr. on June 1, 2007. Trenor met Royce Zeigler while playing World of Warcraft; Robert Sawyers had introduced the game to her and Trenor began putting a lot of time and energy into it. Zeigler believed Riley Ann should be disciplined to say "sir" and "ma'am" to adults, as well as the phrases "please" and "thank you," and that corporal punishment was the best means of disciplining a child. Believing that Trenor was not properly administering the beatings, Zeigler himself beat the child. Zeigler's former stepmother explained that his father had used similar methods to raise his children, which often involved abuse. Other ex-wives also gave recollections of Zeigler's father's abuse and likened the circumstances to that surrounding the death of Riley Ann. Death of Riley Ann In a videotaped confession and signed affidavit, Trenor admitted that on July 24, 2007, she and Zeigler beat Riley Ann
