Summers gsummers@thelancasternews.com A bizarre incident Saturday night included a threatening pickup, a shot from a security guard, a two-agency police chase topping 100 mph, a rammed house, an attempted escape on foot through some woods, and finally a DUI charge for a Lancaster man. Christopher Perez Cornelius, 27, of 1536 Tin Lane or 1946 Santa Barbara Drive, was charged with driving under the influence and failure to stop for blue lights.
