The Garissa victim who is still missing

Isaac Mutisya is a Kenyan father on a mission to find his daughter Risper, who's been missing since the attack on her university in Garissa.

She was on the campus in April when militants from Islamist group al-Shabab attacked, killing 148 people.

Risper comes from Kitui county, east of Nairobi.

She was 23 and studying business management. She's presumed to be dead but she's the only student whose family is still looking for her.
