NH man held without bail in ex-wife's death

SEABROOK, N.H. (WHDH) -- A New Hampshire man charged with killing his ex-wife is being held without bail.

Prosecutors charged 36-year-old Aaron Desjardin of Epping with first-degree murder in the death of Amanda "Amy" Warf, whose body was found in a vacant concrete plant last week. Her neck artery was severed.

“The autopsy reveled that her cause of death was from incised wounds to the neck,” said New Hampshire Senior Assistant Attorney General Susan Morrell.

Authorities said on March 7 firefighters responded to a fire at an abandoned factory building in Exeter and discovered Warf’s body inside. The plant has been vacant for more than 20 years.

“I believe the fire marshal’s office has determined that that was an intentionally set fire using an accelerant,” said Morrell.

Desjardin was arrested Tuesday on his way to Warf’s wake. Authorities would not comment on a motive.

He has been held without bail. He was ordered to stay away from his current wife, his sister and the victim’s mother because they are potential witnesses.

The couple divorced in February 2012. They have a 1-year-old son. The family is taking care of the child, according to Morrell.

Authorities said the investigation is ongoing.
