Westmoreland County inmate challenges math used in murder trial

GREENSBURG — A man serving a life term in the murder of his former girlfriend in western Pennsylvania eight years ago is seeking a new trial, saying he got an unfair trial due to a math error.

Twenty-nine-year-old David Shadle of Slickville was convicted in Westmoreland County in the 2006 death of 19-year-old Jessica Aaron. Prosecutors said he strangled and suffocated the Indiana University of Pennsylvania sophomore because another man had called her.

The Pittsburgh Tribune-Review reports that Shadle told a judge Thursday that a forensic pathologist used an incorrect physics formula in 2007 testimony about the force used to kill the victim.

District Attorney John Peck said the testimony didn’t deal with the amount of force and “There were other causes of death – asphyxiation and strangulation.”
