HOUSTON (AP) – A Houston man accused of fatally shooting a Harris County sheriff’s deputy has pleaded guilty to capital murder and has accepted life in prison without the possibility of parole. The plea by Shannon Miles, who turns 33 Friday, allows him to avoid a possible death sentence for the August 2015 slaying of Darren Goforth. The deputy was shot 15 times while at a suburban Houston gas station where he was putting fuel in his patrol car. Prosecutors said Miles ambushed Goforth simply because he was a law enforcement officer. Miles has a history of mental health issues, initially was found incompetent and spent several months at a state hospital since his arrest days after Goforth’s death. Doctors later determined him competent and a judge ruled him competent to stand trial.
