Lois Long, 87, an art teacher in the adult education programs of the Fairfax County Public Schools and the University of Maryland in the 1970s and 1980s, died Jan. 8 at a hospital in Fairfax County, Va. The cause was a hemorrhagic stroke, said a daughter, Tanagra Cafferky.

Mrs. Long was born Lois Culver in Frankfort, Ind., and settled in the Washington area in 1957. In addition to her adult education work, she also had a ceramics studio at her home in Falls Church, Va., and taught private ceramics lessons.

Daniel Olmsted, journalist, anti-vaccine activist

Daniel Olmsted, 64, a journalist who served as a senior editor with USA Today, became an investigative reporter with the UPI wire service and helped start a blog that purported to link vaccines to the developmental disorder autism, died Jan. 23 at his home in Falls Church Va.

The cause was an overdose of prescription medication, said his spouse, Mark Milett. A spokeswoman for the Fairfax County Medical Examiner said a final ruling was pending further tests.

Mr. Olmsted, a Chicago native, joined USA Today as a founding editor in 1982 and spent many years with its magazine. He went to UPI in 1999 and co-wrote investigative stories about the antimalarial drug mefloquine (marketed as Lariam) and examined cases involving side effects including hallucinations, anxiety and depression.

The stories received an award from the National Mental Health Association. In 2013, the Food and Drug Administration issued a warning about the drug’s potential to cause long-term neurological damage and serious psychiatric side effects but said it was “a very effective drug that is well tolerated by most people who take it.”

After reporting for a UPI series called “Age of Autism,” Mr. Olmsted left in 2007 to start ageofautism.com, which alleged an autism “epidemic” caused by vaccines. According to the Centers for Disease Control and Prevention, “there is no link between vaccines and autism.”
