EPPING, N.H. (AP) - New Hampshire police have taken into custody the ex-husband of the woman whose body was found in a vacant concrete building last week.

WMUR-TV reports Aaron Desjardens of Epping was taken into custody Tuesday, but police would not say why.

Desjardins is the ex-husband of 26-year-old Amy Warf, whose body was found Thursday by firefighters who had responded to a fire in the Exeter building.

The Attorney Generals’ office has ruled Warf's death a homicide, but they will not specified how she died.

Police searched Desjardin's house over the weekend, but he maintained he had nothing to do with Warf's death.

Senior Assistant Attorney General Susan Morrell said she would release more details later Tuesday.

State Police said family members were being briefed on Tuesday's developments.
