Alfred Moore, 64, was arraigned late Thursday on vehicular homicide charges in the June 27 crash involving his cab and three motorcycles in Penn Township, Lancaster County.
Moore also faces two counts of recklessly endangering another person, reckless driving and disregarding a traffic lane. Lancaster County District Attorney Craig Stedman and Penn Township police scheduled a news conference Friday afternoon to discuss the case.
Two married couples died in the collision; Samuel and Linda Lapp, both 48, of New Holland; and Dennis Wilhelm, 43, and his wife Amy, 50, of Manheim Township. Joshua Pennington, 27, of East Earl also died. Kristin Skowood, 27, also of East Earl, was the lone motorcycle rider to survive the crash.
According to court documents reviewed by WGAL-TV, police found Moore had low blood sugar related to diabetes at the time of the crash.
The Intelligencer Journal/Lancaster New Era newspaper reported that Moore has a long history of traffic violations and had his drivers license suspended twice in 2008. The paper reported he had two dozen violations and paid nearly $3,000 in fines since 2002.
The paper also reported Moore was driving a Harrisburg City Cab at the time of the crash. A voicemail message left with a phone listing for the company by The Associated Press was not immediately returned Friday.
Moore was being held at the Lancaster County Prison after failing to post $50,000 bail following his arraignment. It was not clear if he had an attorney.
A preliminary hearing is scheduled for Sept. 10.
