The lawyer for the family of murdered British teacher Lauren Patterson is to appeal the sentence handed down to her murderer's accomplice, according to local media in Qatar.
Badr Hashim Khamis Abdallah al-Jabr was convicted of the killing and sentenced to death.
His friend, Mohamed Abdallah Hassan Abdul Aziz, was jailed for three years for trying to conceal evidence of Patterson's murder.
The Pattersons' lawyer, Abu Skeikha, called the verdicts "partially satisfactory" and said he would seek a longer custodial sentence for Aziz.
