A cell phone led investigators to the suspects in the case of a Wheaton volleyball player killed Saturday in St. Louis.
Megan Boken was shot two times in the chest and neck as she sat in her car.
According to documents released Friday, the investigation turned up a cell phone connected to another robbery in the area that led them to a woman who stated her boyfriend, Keith Esters, told her he shot Boken.
Police say Esters' cousin, Johnathan Perkins, drove him to the neighborhood in order to look for a robbery target and zeroed in on Boken after seeing her speaking on her cell phone. Esters is the alleged gunman and police say Perkins admits driving him away from the scene.
Police say has Esters confessed to the crime and that a witness identified him as the one running away.
Esters and Perkins, both 18, face a host of felony charges. Esters was charged with first-degree murder, first-degree attempted robbery and armed criminal action. Perkins was charged with second-degree murder, second-degree attempted robbery and armed criminal action.
Funeral services were held for Boken in Wheaton on Thursday.
Her father, Paul Boken, released a statement the family is "gratified with the progress in the case and with the efforts of the St Louis Police Department." He also thanked the people who came forward to assist with the case.
