HARRISBURG, Pa. (AP) — An independent expert will review security at Pennsylvania Gov. Josh Shapiro’s official residence after investigators accused a man of scaling a wall and setting fire to the mansion. State police say the review will be a risk and vulnerability assessment following the security breach. Authorities allege Cody Balmer scaled an iron security fence, eluded officers and set the governor’s residence ablaze early Sunday morning. Investigators are combing his background to try to determine any motive for the attack, including whether it had anything to do with Shapiro’s Democratic politics or Jewish faith.
