A 15-year-old girl - one of three people found dead in a flat in Northern Ireland - was strangled to death, police have said.

Allison Marimon-Herrera's body was discovered with two others at the property in Newry, County Down, on Thursday.

Officers said there was a "strong possibility" her mother, 37-year-old Giselle Marimon-Herrera, was also strangled.

Police Service Northern Ireland (PSNI) has launched a murder investigation and is not looking for anybody else in relation to the case.

They said a 38-year-old man, believed to be Giselle Marimon-Herrera's partner who also lived at the flat, died by hanging.


Detective Superintendent Jason Murphy said the mother was originally from Colombia and moved to Northern Ireland four years ago.

He said her daughter was born in Spain and had lived in Northern Ireland since 2017.

"My thoughts today are very much with their families and friends who are trying to come to terms with their loss," he said.

"Allison attended Newry High School and my thoughts are also with the teachers and pupils who knew her. They too are trying to come to terms with this tragedy."

Detective Superintendent Murphy said he believed the mother and daughter were still alive in the early hours of Sunday but family members had been unable to contact them since.

He said: "The exact circumstances of what happened in their home remains the subject of our investigation.

"I would appeal today to anyone who came into direct contact with either Giselle or Allison or communicated with them via text or social media since Friday to contact detectives in Newry."

He added: "This is an unspeakable tragedy and anyone with information should contact detectives on 101."
