The victims of the suspected serial killer in Rwanda have yet to be identified.
Police have exhumed more than 10 decomposing bodies from a hole in the kitchen of the house he was renting in the capital, Kigali.
The man, who police say confessed to the killings earlier in the week, has not commented in court on the allegations and is yet to be formally charged as investigations continue.
Other things remain unclear, like the exact timeline – though locals say the man had rented the house for more than a year.
A police spokesperson told the state broadcaster it was believed that most of the victims were women he had met at bars.
His neighbours told local media that at times they heard women screaming in the night – though they did not think there was anything untoward about the sounds.
Rwandans have reacted en-masse in shock on social media to news of the arrest.
A survivor who managed to escape from him is believed to have led to his arrest and the discovery of the bodies – though police say he confessed after being evicted for not paying his rent.
He had previously been accused of rape but was released for lack of evidence, police said.
