The murder trial of Kaitlin Armstrong, a woman accused of gunning down pro cyclist Anna Moriah Wilson, began in Texas on Wednesday. Prosecutors claim that Armstrong tracked Wilson's movements on a fitness app before the shooting occurred. Armstrong has pleaded not guilty to murder charges, but prosecutors argue that Wilson's final screams and the shots that killed her were captured on nearby surveillance equipment. They also stated that Armstrong stood over Wilson and fired a third shot into her heart. Defense attorney Geoffrey Puryear countered by saying that there is no video evidence or witnesses placing Armstrong at the scene of the crime. The trial began three weeks after Armstrong attempted to escape from custody. Armstrong's relationship with Colin Strickland, Wilson's former boyfriend, was also discussed during the opening statements. Both were competitive gravel racers, and Strickland is expected to testify about his communication with Wilson in the month leading up to her death. The trial continues as the court hears more evidence in the case.
