An American woman has been charged with murdering her Florida-based Irish boyfriend. 

Wendy Hank, 33, of Christmas in Florida has been charged with the first degree murder of 39-year-old Darren William Haverty.

Mr Haverty, who had been living in the US. was originally from Greenhills in Dublin. 

Osceola County Police say officers arrived at around 1am last Tuesday following a shooting at Harris Road in St. Cloud.

Ms Hank told police she and her boyfriend were involved in a verbal and physical altercation.

County Police say she claimed to have been attacked and shot her partner after he approached her with a knife. 

However detectives discovered evidence at the crime scene and during the autopsy which they believe conflicts with Ms Hank's statements of self-defence.

She was then arrested and charged and is being held at Osceola County Jail.

The Department of Foreign Affairs has confirmed that it is providing consular assistance to Mr Haverty's family.
