At a plea hearing Friday, 19-year-old Keith Esters admitted to shooting and killing Megan Boken.
As part of his guilty plea, Esters was sentenced to life in prison, plus 20 years. Megan's family was on hand to read statements before sentencing. Police says Esters did not act alone.
His cousin, Johnathan Perkins faces second degree murder charges. Officers say they tracked down Esters and Perkins by tracing a cell phone that was stolen from someone else six days before Megan was murdered.
