The mother of a young woman murdered at her home in Gwynedd has paid tribute to her.
Emma Baum was described as ”the life and soul in any situation” by her mother Amanda.
A man arrested on suspicion of murder remains in police custody – detectives are due to ask magistrates in Caernarfon for more time to question him.
A woman was also arrested on suspicion of perverting the course of justice and assisting an offender – she has been released on bail but is still under investigation. Two men were released without charge on Tuesday.
Detectives leading the investigation say Ms Baum died from severe head injuries after a sustained attack involving a bladed weapon. They believe her killer would have been bloodstained and discarded clothing and the blade after the assault.
In a short statement on Wednesday, Amanda Baum said her daughter was her rock and her young boy, Steffan, was her world. Mrs Baum said Steffan had now lost the most important person in his life and she didn’t know what she would do without her.
She added: ”She was my best friend and a beloved daughter, mother, partner and sister who had a heart of gold and would do anything for anybody. I am so lost without her and she will be forever in our thoughts and prayers. She will always be in our hearts forever and always. Love you Emma. Always and forever.”
Around 50 officers are involved in the investigation. On Tuesday, North Wales Police confirmed it had referred itself to the Independent Police Complaints Commission, after officers were called out to reports of an overnight disturbance at a house on Llwyndu Road but found nothing suspicious. Ms Baum was found dead around six hours later.
In his latest appeal on Thursday morning, Detective Superintendent Iestyn Davies said they had numerous reported sightings of a man seen running from the rear of Ms Baum’s house: ”I believe this to be a male person who was wearing a dark possibly grey coloured hooded top and dark tracksuit bottoms. This person ran along the rear of Llwyndy Road and in the direction of King’s Road. This was at about 4am (18th July) but I believe that the person responsible had been in the vicinity of Llwyndy Road from about 2.30am onwards.”
Officers are also trying to track down the driver of a black three-door Ford Fiesta car. It travelled between Trefor and Penygroes between 2am and 2.30am on Monday morning, before making a return journey between 4am and 4.30am.
