The R.M. Palmer Co. chocolate factory in West Reading, Pennsylvania, experienced an explosion on Friday that left two people dead and five missing. Rescue crews spent Saturday searching the site for survivors. One person was rescued from the rubble overnight, providing hope that more could be found. The cause of the explosion is still under investigation. UGI Utilities reported that gas was released due to damage from the blast, but they did not receive any prior reports of a gas leak. The building was destroyed, and a neighboring building was damaged. The Reading Hospital received ten patients, with two admitted in good and fair condition, one transferred, and all others discharged. People were asked to move back a block in each direction, but no evacuations were ordered, and the emergency declaration was issued to bring more support for first responders. R.M. Palmer, which has been making chocolate novelties since 1948 and employs 850 people, is expected to make a statement. The company advertised Easter treats on its Facebook page earlier this month.
