A University engineer was killed and seven others injured Saturday night in a two-vehicle collision in Juniata County, Lewistown state police said yesterday.

Allan Naugle, 52, 601 Devonshire Drive was pronounced dead on arrival at Harrisburg General Hospital at 8:25 Saturday night, a hospital spokeswoman said.

Naugle, a University staff member for 15 years, was a mechanical engineer for the University's Institutional Engineering Advisory Services.

Naugle's wife Shirley was listed in fair condition yesterday.

Police said the accident occurred at 6:30 p.m. on Route 322 in Delaware Township, about one mile west of Thompsontown. Naugle's car apparently skidded on the ice-covered road and slammed into a van driven by Loren Dean Deckard, no age given, of Joppatown, Md., police said.

Deckard had stopped on the road shoulder to assist two motorists that had earlier crashed into a tree, police said.

Police said Deckard was not injured, but his wife Mary Jane, daughters Jill Deckard and Karen Mentlick, and granddaughter Ashley Mentlick were treated and released Saturday at Polyclinic in Harrisburg, a spokeswoman said.

The Mentlicks are from Baltimore.

Also injured were occupants of the stranded vehicle, Lynette David and Ann Reece, both of Philadelphia, police said. Police have not determined which of the women was driving that car.

The two were listed as serious in the intensive care unit of Harrisburg General Hospital yesterday, a spokeswoman said.

No ages for the injured were available.

Police said David and Reece flagged down Deckard, who was traveling east, after their car skidded on ice and rammed the tree. They were talking to Deckard through his passenger window when Naugle, who was also eastbound, struck the rear of the van.

Deckard's van was pushed sideways into the two women, police said.

Charles Claar, director of the University's Institutional Engineering Advisory Services, said Naugle's duties included University research in state institutions such as prisons, state universities and mental hospitals.

"On a personal level he was an extremely nice individual," Claar said. "On the professional level he was very thorough and very well respected by his colleagues."
