D. C. Police Officer Richmond Phillips shot his baby’s mother to death and left their infant daughter to die in a hot car because he didn’t want to pay child support, prosecutors said during opening statements in Phillips’ trial on Monday.

Authorities arrested Phillips in June 2011 after finding 20-year-old Wynetta Wright’s body at a nearby park, the one where they met to discuss caring for their daughter.

Phillips lured Wright to a wooded area in Hillcrest Heights in May 2011 and shot her to death. He then left their daughter, Jaylin, in a car on a day that was 100-plus degrees. Her body was found a short distance away. She was a few days from her first birthday.
