The wife of the alleged Gilgo Beach killer appeared to love planning vacations and comic book conventions but hated shopping in large crowds and cold weather, according to a long-dormant Twitter account.

Long Island architect Rex Heuermann was arrested Thursday in connection with three of the Gilgo Beach killings, and is a prime suspect in a fourth death, many of which were committed while his wife Asa Ellerup was out of town, authorities said.

The Twitter account attributed to the name Asa Ellerup uses the handle “@ElvenMaiden,” apparently after an obscure character in a VIDEO? game, with the user claiming to be based in Long Island.

In more than a dozen posts, the Twitter user waxes on about her affection for traveling.

The last posts were in April 2020.

“Wow, spring is creeping up fast! Time to plan a summer vacation. Now where to go, hmm, within the U.S. sounds good. Ideas anyone?,” says one tweet from Feb. 22, 2010.

Many tweets centered around her passion for comic books and conventions.

“Met Christopher Golden at Boston Comic Con. Awesome. Now it looks like they are going to move that convention to the convention center next,” she wrote on April  24, 2010, referring to the novelist and comic book author.

On Jan. 14, 2010, she tweeted, “SanDiego Comic Con sold out Ugh, now would have been a good time to make plans to go. Looking forward to the spring NYC Comic con is next.”

Two days later, she corrected herself and set her eyes on traveling to Boston.

Who is Gilgo Beach serial killer suspect Rex Heuermann?

A suspected serial killer has been arrested over the notorious Gilgo Beach murders in Long Island, The Post can confirm.

Rex Heuermann, 59, a married dad of two and architect at a New York City firm, has a home on 1st Avenue in Massapequa Park, sources told The Post.

Rex Heuermann, a Long Island architect who was charged July 14, 2023, with murder in the deaths of three of the 11 victims in a long-unsolved string of killings known as the Gilgo Beach murders.

His arrest is tied to the “Gilgo Four,” four women — Melissa Barthelemy, 24, Megan Waterman, 22, Amber Lynn Costello, 27, and Maureen Brainard-Barnes, 25 — found wrapped in burlap within days of each other in 2010. 

The body of Barthelemy was first found along Ocean Parkway on Dec. 11, 2010, sparking fears of a serial killer in the area.

By spring 2011, the number of bodies had climbed to 10, including eight women as well as an unidentified man and toddler.

Heuermann’s arrest comes after Suffolk County’s new police commissioner created a special Gilgo Beach Homicide Investigation Task Force in February 2022.

“Nope, Boston Comic con is next. Christopher Golden will be there yeah. Good lineup. I can get both Mike and Christopher to sign Baltimore,” the Twitter user wrote in January 2010.

Despite being of Icelandic heritage, Ellerup appears to be no fan of the snow or cold weather.

“Didn’t get too much snow this time, I’m not in the mood to shovel snow, but it is cold outside,” she said on Feb. 6, 2010.

Six days later, she provided another weather update: “It Snowed, got 13 inches. Don’t like when others don’t move vehicles when the plow is coming [sic]. I always get more snow to shovel.”

“It’s been raining and snowing, I stepped in a huge puddle of slush disguised as snow! I’m freezing I need a warm bath and hot soup,” she later wrote on Feb. 26, 2010.

Ellerup appeared to enjoy spending time with family on Thanksgiving but hated the havoc that went along with shopping in crowded stores.

“Went to the Macy’s Day parade on Thanksgiving it was awesome, ate turkey with family. Dad, Sis, and old friends. More Turkey or dinner tonight,” she tweeted Nov. 28, 2009.

“Ugg. The mall is a nightmare, much worse than Black Friday. Will the madness ever end? Time for online shopping. Amazon here I come,” she said on Dec. 7, 2009.

It also appears Ellerup didn’t have the greatest start to 2010.

“Car accidents are no fun. nor is having the flu too. Happy New Year Everyone. cheers to 2010,” she said on Jan. 4, 2010.

Hair found on three of the victims was later found to have DNA belonging to Ellerup, authorities said.

She is not suspected of any involvement with the murders.

Heuermann, a Long Islander and married dad of two pleaded not guilty on Friday to a slew of charges — including three counts of first-degree murder — related to the deaths of Melissa Barthelemy, Megan Waterman, and Amber Costello, whose bodies were all found dumped along Ocean Parkway near Gilgo State Park in December 2010.

Heuermann is also the prime suspect in the death of Maureen Brainard-Barnes, who was the first of the so-called “Gilgo Four” to disappear, the document stated.

When Waterman was reported missing in June 2010, Ellerup was in Maryland, prosecutors said.

She was in New Jersey in September 2010 when Costello vanished and in Iceland in July 2009 when Barthelemy was last seen.

Ellerup didn’t join Twitter until November 2009 and didn’t post any messages during the time period the victims went missing.

Only 18 tweets were left on the account Saturday morning.
