A soldier accused of killing his 14-year-old girlfriend's mother says the girl did it, not him, and he helped dispose of evidence only because she claimed to be pregnant.

Army Spc. Caleb Barnes' testimony Friday came after the now-15-year-old Jamie Silvonek surprisingly took the stand in his defense.

On Thursday, she was slotted to testify for prosecutors as part of her plea deal but wasn't called.

Earlier Friday, she told the court she was "inexorably, ineffably in love" with the 22-year-old Barnes.

Barnes is accused of stabbing Cheryl Silvonek in March 2015 in Pennsylvania.

The Morning Call of Allentown reports (http://bit.ly/2aRANn5 ) Barnes says he was asleep in his own car when Jamie knocked on his window, covered in blood.

Silvonek pleaded guilty in February. She's serving 35 years to life.
