The government has been slow to resolve the issue linked to the country’s ethnic tensions.
“We are grieving. I can’t stop thinking about her. The entire family can’t eat,” a visibly pained Mare Abebe told the BBC.
She is worried about Belaynesh Mekonnen, a first-year economics student at Ethiopia’s Dembi Dolo University, who was kidnapped last December, along with 17 of her colleagues.
As Belaynesh’s guardian, Ms Mare is distraught for the girl, whom she said she had raised despite many challenges.
“We are in pain. She is a good girl, so caring, but now we don’t know where she is. We don’t know whether she is alive.
“I never thought this could happen to her, even in my dreams,” she said, her voice cracking.
On 4 December last year, an unknown group of people blocked a bus and kidnapped students on board who were leaving for home from Dembi Dolo University in western Ethiopia.
The students, mostly ethnic Amharas, were fleeing ethnic violence and threats in the university that is located in Oromia region.
A total of 18 students – 14 women and four men – were ordered out of the vehicle at Sudi near Gambela city, about 100km (60 miles) from Dembi Dolo.
Belaynesh was among the 17 who had been reported missing, after one of the students, Asmira Shumiye, managed to escape.
It was Asmira’s account of their kidnap and her subsequent escape that brought the matter to the public’s attention.
Asmira said the young men who kidnapped them “looked like gangsters” and spoke in the Afaan Oromo language.
“They selected us and forced us to leave the bus. One person followed us and begged them to leave us, but they refused.
She said their captors repeatedly told them that they had no problem with them (the students). “Our problem is with the government,” she quoted them as having said.
Their intention, she noted, was for Ethiopians to hold demonstrations to pressure the government to come and speak to them.
How Asmira escaped
Inside the forest, the kidnappers kept their captives constantly on the move until some were physically exhausted.
“They made us walk for a long time. Some of the students were very tired. They stumbled and fell. While the abductors were trying to help some of them, I managed to run away. They didn’t notice when I left,” she told the BBC.
After freeing herself, she spent two nights in the forest, uncertain of where she was until she came to a clearing near a main road.
“I met an elderly man on the road. He was alone. He asked me why I was there. I told him what had happened to us and he asked me where I wanted to go. I begged him to link me up with the federal police.
“He made me put on his jacket and and hide under a tree. He was saying: ‘If those people [the kidnappers] see me, they might kill me.’
“I was frightened. He stood by the roadside and hailed a car for me. Finally, I managed to go back to the city and reported to the federal police.”
What is behind the kidnapping?
It remains unclear why the students were abducted but it came at a time of rising ethnic tension in Ethiopia, especially in Oromia.
The Oromo people are the largest of the more than 80 ethnic groups in Ethiopia, constituting more than a third of the country’s 100-million-strong population.
Many ethnic Oromos accuse the government of discriminating against them and there have been attacks on members of other ethnic groups in the area.
The kidnappings had been rumoured to be linked to Oromo rebels fighting the government in the region led by Kumsa Diriba, also known as Jaal Maro. The group denies it.
Even Prime Minister Abiy Ahmed appeared to be at a loss: “When Boko Haram [an Islamist militant group in West Africa] abducts people, it takes responsibility and announces that they did the action, but in this case, no-one took the responsibility of the kidnap.
“They [kidnappers] are unknown people. If we could say something bad happened to [the students], there is no evidence to show that,” Mr Abiy said in February while answering a question in parliament.
How many students are missing?
After Asmira’s escape, it took at least a month for the government to acknowledge the issue.
In the weeks and months after the initial incident, there were protests and a social media campaign to pressure the authorities to take action. But it had little effect.
On 6 January, the eve of Ethiopian Christmas Day, Amhara regional security head Temesgen Tiruneh finally acknowledged the issue saying: “We are aware four students have been kidnapped.” Five days later, the prime minister’s office said 21 students who had been kidnapped had been released and only six were still missing.
It is not clear why there is such a disparity in the numbers.
On 30 January, Deputy Prime Minister Demeke Mekonnen said the kidnapping of the students was one of the challenges the country was facing, and they would look for a solution.
