Police had responded to a report of a burglary at an apartment complex in Palomino Ranch Point, Colorado Springs on December 19.

Two of her children, Elianna and Aden, were found dead inside a flat. An autopsy recently revealed they had died from gunshot wounds.

Singler and her other daughter, 11, were also injured.

The mother had initially cooperated with police but vanished, triggering a US-wide hunt.

She was arrested by NCA officers for offences including two counts of murder and one of attempted murder.

Singler is also accused of two counts of class two felony child abuse, one of class three felony child abuse, and one of assault.

When she first appeared in court on January 1 she did not consent to her extradition to the US.

Ex-husband Kevin Wentz had shared a picture of himself with his three children in a Facebook group dedicated to the case.

He wrote: 'Hello group. I'm the father. I also want to say she has been arrested.'

Singler was remanded in custody ahead of another preliminary hearing at the same court on March 25.
