Two Brisbane teenagers charged over alleged murder of North Lakes woman

Two teenagers have been charged with murder after 41-year-old Emma Lovell died after being stabbed in the chest at her home in North Lakes on Boxing Day.

Queensland police on late Tuesday confirmed two 17-year-olds had been charged with murder, attempted murder and break and enter.

Both have been denied police bail and are due to appear in the Brisbane Childrens Court.

Police said a scuffle broke out on to the front porch, where Lovell, a mother of two, suffered a stab wound to her chest.

Paramedics were called to the scene and attempted to save Lovell but she was pronounced dead in hospital.

Earlier, superintendent John Hallam told reporters the two intruders allegedly disturbed a couple in their 40s inside their home at North Lakes, in the Moreton Bay region, about 11.30pm on Boxing Day.

He said the couple had been awoken by barking dogs.

Hallam said the two alleged intruders fled the scene but they were apprehended by the police dog squad at a nearby home.

Hallam said there were currently no known links between the victims and those in custody.

Two other boys had been taken into custody and are assisting police, Hallam said.

Police said A fundraising campaign has been established for the family by members of the North Lakes community.

Only hours earlier, Lee Lovell had posted on social media that the family, originally from England, had spent Christmas day on the beach for the first time in 11 years.

A crime scene has been declared at the home.

Investigators have urged those with information, dash cam or CCTV footage to contact police.
