Thousands of people attended the janaza of Nahid Al Manea, the female international student from Saudi who was murdered in Colchester last Tuesday.
Her body arrived in her home town of Al-Jouf early Saturday morning and was later buried.
31-year-old Nahid Al Manea was walking on the Salary Brook Trail at 10.40am on Tuesday 17 June when she was violently beaten and stabbed 16 times.
Paramedics tried to save her but she died at the scene from injuries to her head and body.
Essex Police said a 19-year-old from Colchester had been arrested on Friday afternoon over the death but later released without charge.
He was also questioned about an attack on a woman who was jogging on Peache Road but police said he would face “no further action” in either inquiry.
An Essex Police spokesman said: “No further action against him is planned in respect of either the murder or the assault as he has been eliminated from both inquiries.”

Ms Al Manea recently came to the UK in pursuit of her PhD for a brighter future at the University of Essex.
The PhD student was wearing a navy blue abaya and a multi-coloured hijab when she was murdered.
Detective Superintendent Tracy Hawkings said officers were keeping an open mind about the motive of the attack.
But she added: “We are conscious that the dress of the victim will have identified her as likely being a Muslim and this is one of the main lines of the investigation but again there is no firm evidence at this time that she was targeted because of her religion.”
The University of Essex said Ms Almanea was a “very hard-working and conscientious” student and was due to finish her studies in August.
A 52-year-old man previously arrested over the death has also been “positively eliminated” from police inquiries.
