Althea Blankinship and Her Son, Jeffrey Blankinship, Disappeared Under Suspicious Circumstances in 1973
Althea Blankinship
Jeffrey Blankinship
Althea was 23 years old the last time she was seen or heard from. Her birthday is October 24, 1949. She was 5′7″ and 140 pounds. She has blonde/brown hair with blue eyes. She may also use her maiden name of ‘Marks’. She is of Greek decent.
Jeffrey’s date of birth is listed as two possible dates, August 3, 1969 or December 3, 1969. He was 3′5″ and 75 pounds with brown hair and brown eyes.
Althea and her son Jeffery were last seen on March 27th, 1973. They resided in Port Townsend, Washington where Althea lived with her roommate Glenn Allan Bagley. Bagley said he dropped Althea and Jeffery off at Seattle-Tacoma International Airport, where Althea and Jeffery were going to catch a United Airlines flight to New York. From New York they were going to travel to Greece where Althea was going to meet up with her parents who were already there.
There was no record of Althea or Jeffery boarding a flight that day, and they never arrived in Greece.
Glenn Bagley has remained the main suspect of this case. He is also the prime suspect in the disappearance of his ex wife, Esther Gesler, who disappeared in 1976.
Bagley would continue to claim that Althea and Jeffrey both made their flight and went on vacation until Althea’s cousin was searching through a relatives home and found Althea’s passport in 2002. There were no entries on the passport. Althea had also never been issued a new passport making it very unlikely her and Jeffrey ever left the country. The same cousin of Althea’s also found a bunch of letters between Althea and Glenn Bagley and found out that they were in a romantic relationship.
Right after the disappearance of Glenn Bagley’s wife, Esther, disappeared, Glenn moved to the Philippines and lived in Manila for many years. He never spoke to Washington State Police, although they were always working to build a case against him.
Unfortunately there will be no more answers from Glenn Bagley. He died of cancer in February 2016, in the Philippines.
All the puzzle pieces lead to Glenn Bagley, but we need to find Althea and Jeffrey to bring closure to their family.
