- Elgiva had confessed to being a terrorist and was sentenced to ten years in prison.
- His mother, driver and lawyer were kidnapped on Thursday for what officials termed as debriefing sessions.
The sister-in-law of former Westlands MP Fred Gumo, who was kidnapped on Thursday and later released, is the mother of a missing terrorism convict.
Jacinta Bwire and her driver Willis Otieno were released by their captors on Saturday night and Sunday. The family said they were Ok, without giving more details.
Her son, Elgiva Bwire Oliacha, who was released from jail on Thursday before he was picked up by gunmen in the city, is still missing.
Gumo said Jacinta was released on Saturday night, while their driver called Sunday morning to say he had been freed.
"We don't know where Elgiva is, but Jacinta and the driver were released by the captors. They are fine and resting now," he said.
He said they may give further details later.
An official said they are concerned Elgiva is still radicalised and may go back to his activities.
"He never changed while in jail. He is still the same," an official who had profiled him said.
Officials said they expected to have their lawyer, Muslim scholar and lawyer Hassan Nandwa who is also missing, to be released.
The families of the victims have now linked the drama to the release of Elgiva on Thursday from Kamiti Maximum Prison, where he served 10 years.
This was after Elgiva, who had been sentenced to life imprisonment, appealed and the sentence was reduced to 10 years.
Jacinta, a former Nairobi Water and Sewerage Company employee, was driving home in Muthaiga area when her car was blocked. She and her driver were taken to an unknown destination.
There has been no official comment from police. But police confirmed the families of missing persons had made reports to various stations.
According to reports, Bwire was picked up from Kamiti Maximum Prison by his mother, brother and a nephew. Officials said Elgiva alighted in the city centre before he was picked up by the captors.
After learning that her son was missing, Jacinta is said to have headed to Gumo’s home to inform him.
She was kidnapped by unknown people as she drove there.
Soon after getting information on Elgiva's disappearance, Prof Nandwa headed to the Central police station to file a missing person's report, before heading to Jamia mosque for evening prayers.
However, he also went missing and was last spotted at 7pm on that day.
Supreme Council of Muslims chairman Hassan ole Naado said he was shocked to learn Jacinta was the mother of the ex-convict.
He said Jacinta and her husband went to his office in April to ask for help and safety for her son, who was about to be released from jail.
“They said they were concerned their son may go missing as soon as he is released because of the nature of the charges he faced. There was little we could do then,” he said.
Their fears came to pass five months later. Elgiva was still missing on Sunday.
The family of Nandwa said he was not in any way linked to terrorism.
Hassan Nandwa, the firstborn son of the missing man, and his mother, Mawahib Nandwa, said he was not a sympathiser of terrorism.
They said all he did was represent Bwire and what he did was within his rights as an advocate.
Elgiva was in the news in 2011 when he confessed to being a terrorist and a member of al Shabaab terror group.
He also admitted to illegal possession of firearms, including an AK-47 rifle, a submachine gun, two revolvers, 13 hand grenades and 770 assorted rounds of ammunition.
Police were shocked by his confession that on Mashujaa Day 2011, he had carried one grenade to Nyayo Stadium "for a test run."
In the stadium, he posed as a hawker selling sweets. Police were to later find the grenade and sweets when they raided his house.
Elgiva told police he went to the stadium and mingled with wananchi who had arrived for the occasion that was presided over by former President Mwai Kibaki under tight security.
He decided not to detonate the explosive because of the rain and because a chance meeting with his mother distracted him.
Jacinta told police she bumped into him after almost a year as he walked out of the stadium.
Elgiva left the stadium with his deadly cargo and went to his house, which did not have a single piece of furniture, save for a prayer mat.
Jacinta said then that was her first meeting with her son since February 2010.
She said Elgiva, the third born of her five children, told her then that he had been in Mombasa and had only returned to Nairobi in August.
Elgiva attended primary school in Dandora and disappeared from home in February 2010 until a year later. He had gone to Somalia where he was radicalised.
He said then he received instructions via an email telling him to pick a luggage from Eastleigh, Nairobi.
Therein were 20 grenades and bullets. He later used seven before he was caught.
He had posted a message on Facebook stating he would attack 13 more locations before he was arrested.
