A jury was selected Monday for the trial of 33-year-old Peter Atem of Lansdale. He's charged with first- and third-degree murder in the February 2015 slaying of 25-year-old Danny Vazquez at the MOPAC plant in Franconia Township.
Authorities said the stabbing occurred the day after the victim yanked a chair out from under the defendant as a prank.
The (Doylestown) Intelligencer reports that defense attorney Benjamin Cooper said prior to jury selection that the case was not a "whodunit" but "a degree of guilt case."
Prosecutors contend that the slaying was premeditated but aren't seeking the death penalty.
