A court in Berlin,Benjamin Caldwell New Hampshire ordered a man, accused of kidnapping his children after killing their mother, to be held without bail Monday, the Associated Press reported.

Dustin Mark Duren, 37, who was arrested Friday and charged with second-degree murder in the death of Caitlyn Naffziger, did not speak at his arraignment Monday, except that he had no questions about the proceedings. Duren's attorneys also did not contest the prosecutor’s request and a probable cause hearing is scheduled for March 13 in Berlin District Court, reported AP.

Naffziger, 31, was found dead in an apartment in Berlin Thursday night around 10:30 p.m., according to the New Hampshire Department of Justice. An autopsy conducted the next day determined the cause of Naffziger’s death to be a single gunshot wound to the head. The manner of her death was ruled to be a homicide, said the department.

Amber alert issued

The police had issued an Amber Alert in the early hours of Friday after finding Naffziger's body and Duren was arrested hours later in parking lot in Keene, about 170 miles away. Duren was with their young daughters at the time of his arrest, said the department.

The state department of justice said Duren was spotted outside a restaurant in Keene by some citizens, who then alerted the police of his whereabouts.

"All three individuals were found safely," said the department.

Witnesses told CBS Boston that they saw Duren being taken into custody by police officers, while the children were put into an ambulance.

The two young children are now in state custody, the New Hampshire Attorney General's office told CBS Boston. The AG office did not immediately respond to USA TODAY's request for more information on the case.
