A mother accused of murdering two of her children in the US has appeared in court for extradition proceedings after being arrested in the UK.

Kimberlee Singler, 35, was detained on Saturday in central London.

Her daughter, aged nine, and son, seven, were found dead at a home in Colorado on 19 December, along with her 11-year-old daughter who was injured, US police said.

They issued a warrant for her arrest a week later.

Singler has been charged with two counts of first degree murder, one count of attempted murder, three counts of child abuse and one count of assault.

The UK's National Crime Agency (NCA) said she appeared at Westminster Magistrates Court on Monday for an extradition hearing.

She was remanded in custody and will next appear in court on 29 January.

A spokesperson for the NCA said: "On Saturday 30 December 2023 in the Kensington area of London, officers from the National Crime Agency's National Extradition Unit arrested a 35-year-old female wanted in the United States of America for offences including two counts of murder and one count of attempted murder."

In a press release last week, Colorado Springs Police Department said it first responded to a 911 call reporting a burglary at a Colorado residence at 00:29 local time on 19 December.

Singler and her eldest daughter were found injured and received treatment at the scene before being taken to hospital, it said.

The force later determined the initial report of burglary to be "unfounded".

In its latest release it confirmed she was arrested "without incident" in the UK, and said more information would be shared in a press conference to be scheduled in the future. (BBC)
