Denied by Hansen, Pt. 2: Mary Thill

In 1975, Robert Hansen returned to Seward for another 4th of July. Another woman went missing. Another woman “denied by Hansen.” Her name is Mary Thill; she was 22-years-old at the time of her disappearance.

Here’s what we know about Mary:

  • She was last seen in Seward on July 5, 1975.
  • Like Megan Emerick, she was a student at the Seward Skill Center.
  • Her husband was working the North Slope at the time of her disappearance.
  • A friend gave her a ride to the Seward Bakery, in the historic center of downtown Seward.

  • Another friend reported seeing her at the Lowell Creek waterfall, a half-mile south of the bakery, and a two-minute walk from the bakery.
  • Mary was spotted at the falls between 1:30 and 2:00 p.m. She was never seen again.

And here’s what we know about Robert Hansen (according to court records and his confession):

  • On parole for an Assault with a Deadly Weapon charge involving a real estate secretary, Hansen was required to tell his parole officer his whereabouts; his parole records show that he was in Seward on the July 1975 weekend that Mary disappeared.
  • Before heading south, Hansen asked a friend if he knew any women he could party with in Seward.
  • Seward was, and remains, a small town. The Seward Bakery is one mile from the nearest boat launch — a distance Hansen could drive in three minutes.
  • Hansen had access to a vehicle throughout his stay in Seward.
  • In his confession, Robert Hansen evidenced a detailed knowledge of Seward — including the old Army gun emplacements at the former Fort McGilvray, just south of Lowell Creek, along the same road.

“[There are] gun emplacements down here at Seward… where they used to have some rather large caliber cannons that were supposed to protect the town of Seward. They got some up there and they got some up on top of the hill… [And] someplace in here there is more Army docks… Anyway, outside the iron doors here I used to scuba dive quite a bit.”

It is tempting to think that Hansen went to the bakery, spotted Mary, followed her to the parking lot at the Lowell Creek waterfall, picked her up and then took her to his boat. That we’ll never know. What we do know, from the Joanna Messina case, is that he had ulterior motives for striking up conversations with unknown women.

“I believe this impulsive act of seeing, following, and later trying to abduct a non-prostitute surfaced several times throughout his chicken killing career, which included Emerick and Thill of Seward and possibly other unclaimed map X’s.”

One thought on “Denied by Hansen, Pt. 2: Mary Thill

  1. Went to high school with Mary. Her maiden name was Mary Kay Lannan. They say the good die young….this was certainly true in this case. Both her parents died when she was in high school leaving her and her siblings alone . Yet, she was always smiling and spreading sunshine. Maybe that’s why she fell a victim….her friendly inviting face that trusted everyone. She was truly a good soul and I weep when I think of her short life. I am now 66 years old and am lucky that I knew her for the time we spent together in high school. She had lots of friends, was a good student and was crowned Queen of the prom.
