HOOKSETT — As state authorities continue their investigation into the murder of an elderly couple on Kimball Drive Sunday, new information has emerged about the now-deceased man whom investigators believe was responsible for the killings.

In a news release Thursday, Attorney General Gordon J. MacDonald confirmed that June Cosma, 79, and her husband, Thomas Cosma, 80, both died of blunt force trauma to the head at the hands of 34-year-old Zachary Gloudemans, who state investigators say had been staying at a residence in proximity to the Cosma house and “was displaying signs of (drug) abuse.”

Gloudemans was found dead of an apparent suicide in Lawrence, Mass., after leading Andover, Mass., police on a high-speed chase in a stolen car registered to Thomas and June Cosma.

Following that incident, New Hampshire law enforcement officials went to do a welfare check on the Cosmas at 47 Kimball Drive and found both of them dead, officials said Monday.

While the AG’s office stated that Gloudemans had a prior criminal record, they have declined to confirm that he is the same Zachary Gloudemans who in 2011 was convicted of robbing the Bank of America in Manchester and leading Londonderry police on a high-speed chase.

But Robert Milanese of Manchester, who described himself as “a good friend” of Gloudemans, stated that the two Gloudemans were one in the same.

“That’s him, dude,” said Milanese. “One-hundred percent sure. How many 34-year-old Zachary Gloudemans do you think there are?”

Milanese said he got the news about Gloudemans’ involvement in the murders early Friday morning, and stated that he had tried unsuccessfully multiple times to reach him by phone.

“He always answers his phone,” said Milanese.

Milanese described Gloudemans as a “good person” who he never saw angry.

“I don’t understand how he could do this to old people. It blows my mind,” he said.

Although he said he wasn’t sure how Gloudemans could have known the Cosmas, Milanese stated that Gloudemans was a “handyman” who had “helped out old people before.”

Milanese, who says he’s in recovery from drug misuse, stated that Gloudemans last contacted him a few weeks ago trying to borrow some money. Milanese said he declined the request for fear that Gloudemans would use the cash to buy drugs.

Gloudemans himself has a very large social media footprint, posting on a Facebook page titled “Penpalsforprisoners by Monica Y Carter” in 2017 that he was “serving 15 months on a violation” at the Hazelton federal prison in West Virginia following a 2011 bank robbery that he was originally released for in 2014.

In the same post, Gloudemans said he planned to relocate to Brooklyn, N.Y., to “find a new life” upon his release date.

Gloudemans was also active on Quora, a social media website where users can publicly ask each other questions or give out answers on a variety of topics.

He actively answered questions on the site on topics ranging from career advice and what to expect on a court date to how to deal with anger.

On one occasion in March of 2016, Gloudemans told a user pondering suicide about his lifetime of struggle with poverty and drug misuse, and encouraged them not to give up hope.

“Don’t even start with thinking that I don’t know your story because I do,” wrote Gloudemans to the user. “I have been there and I keep going through it. But if it takes me 50, 60, 70 years to finally achieve peace and happiness, so be it. I only get to live once so why cut it short when I don’t know if I’ll win the lottery next year or that I might invent something to better humanity.”

Gloudemans’ last Quora post took place on Jan. 29, in which he discussed his current status as a homeless person.

“I have too much pride to panhandle (though I have when desperate) and I work everyday if I can,” he wrote. “But with no vehicle I am at a disadvantage due to the state that I live in and lack of public transportation and pedestrian ways throughout the state. A vehicle is mandatory to succeed in this state. It’s also a place where homeless are treated as a pest or nuisance and are displaced and treated as criminals.”

State authorities say they plan to release more information following the end of the investigation.
