Bryan said the family wanted to get information out to the public about her daughter's missing car, a green, four-door 1995 Pontiac Grand Am. The Pennsylvania license plate number of the car is EHE-7205.
"The more we can get this out about the car, the more help it will be," said Carol Bryan's husband, Jeff Bryan.
An employee with the homicide division of the Las Vegas Metropolitan Police Department, which has jurisdiction in the case, said the division is investigating Sheeder's death, but several calls to speak to an investigating officer Monday and Tuesday were not returned.
Pennsylvania State Police Trooper Aaron Martin said Tuesday that state police here are assisting Nevada authorities in the investigation.
Jeff Bryan said the family knows few details about the case at this point, but that Sheeder was supposed to be driven in her car to an airport for the trip to Las Vegas.
"A friend was supposed to take her," he said.
He said, however, that there apparently is no record of her having flown to Nevada.
"They're still investigating the case. That's why we have to be real careful" about what details they can talk about, Carol Bryan said when asked if the unnamed friend actually drove the mother of two to the airport.
Carol Bryan said her daughter lived in the Greencastle area for about three years and worked at First Data in Hagerstown. Her daughter was raised in Bedford County, Pa., and was a graduate of North Bedford High School.
Sheeder's two children, Cameron, 6, and Kyle, 5, live in Everett, Pa., with her ex-husband, Scott Sheeder, she said. Joselyn Sheeder also is survived by her father, Barry Clark of Hopewell, Pa.; a brother; a sister; and several stepbrothers and stepsisters, some of whom live in the Franklin County area, according to information from her obituary.
"She loved her kids and she loved her family, and she was a good mother," Carol Bryan said. Sheeder frequently visited her children after her marriage ended, her mother said.
"Some cases are all over the national television and news," Jeff Bryan said, but the family has been found little information from Las Vegas media about the case.
Meanwhile, the family is waiting to find out how she died and for any breaks in the investigation.
"We're interested in trying to get this resolved so we have closure," Jeff Bryan said.
