Police in Lititz are investigating a police-involved shooting that left a 22-year-old man dead.
Lancaster County officials received a 911 call at around 3:10 a.m. Saturday morning, but there was no apparent caller on the line. The call was then disconnected.
Less than a minute later, a second call was received from the same number, and again dispatchers heard no voices, and again the call was disconnected.
When a third call was received from the same number, dispatchers spoke with a woman who said she needed police at her home for an apparent problem with her grandson.
A Lititz Borough officer had already been dispatched to the address in the 100 block of Arrowhead Drive, and the officer arrived while the dispatcher was on the phone with the caller.
The officer was confronted by a 22-year-old man armed with a large knife. The man refused orders to drop the weapon, so the officer deployed his taser which had no apparent effect on the man.
The 22-year-old advanced on the officer and, despite orders to stop, raised the knife. The officer fired on the man several times with his service weapon. Authorities don't know how many shots were fired or how many times the deceased was struck.
Police have since identified the man as David Giliberti.
An investigation is being conducted by Lancaster County detectives and Lititz Borough Police. The officer involved in the shooting will not be identified at this time; he has been placed on administrative leave which is routine for officer-involved shootings.
The grandmother, who is reportedly the only witness to the shooting, was interviewed by investigators.
