A sombre mood has engulfed Sengera area in Kisii, the home village of Father Cosmas Ondari Thursday who was killed by suspected Cameroon soldiers on Wednesday evening.
Family members and relatives of the slain priest said they received news of his death with utmost shock.
Fr Omboto was holding an evening church mass when a soldier shot him in the head killing him on the spot.
The country has been experiencing a surge in conflicts in volatile English-speaking Southwest region where a group is vouching for separation from Yaoundé.
Family members of the deceased on Friday condemned the incident terming it uncalled for.
His father Charles Omboto said his son was on a missionary mission when he was killed.
"The news we have is that he was holding a mass but the congregants upon seeing the soldiers scampered leaving him alone and that is the time he was shot dead," Mr Omboto said.
His body was discovered by a group of worshippers who had returned to the church compound shortly after the soldiers left.
"He had remained alone because he had not known that people there always run away when the see the military and that is how he got killed," Mr Omboto told the Nation at his Sengera home in Bomachoge Borabu.
Relatives and church members on Thursday flocked to the home to offer condolences.
Most parishioners described the late cleric as "very spiritual" and a man fired by the missionary spirit.
"He grew amongst us and was concerned with spiritual things and that is how he ended up in serving the church as a missionary," said Sister Mary Naitumbi.
Family members said they may not be able to travel to bury the body in Cameroon and requested the Mill Hill Society to make arrangements so that the body can be brought to Kenya.
"We are not compelling them but if they can bring him back home, it will be better for us," Mr Omboto said.
Fr Ondari's brother Bonface Omboto said they had learnt of the death of his brother with a heavy heart.
He was away in Uganda when he got a phone call breaking the news of his brother's death on Thursday.
Kisii Parish Bishop John Mairura described the late priest as one who was dedicated to the vineyard of God.
"He was a young priest fired with missionary spirit but death has snubbed him at a time we knew he had much still left to do in reaching out to lost souls," Fr Mairura told the Nation by phone.
Kisii University Catholic Chaplain Lawrence Nyaanga condemned the attack and the killing of the Kenyan priest by Cameroon soldiers.
"Priests are in a different war frontline, to save souls not to fight. Fr Ondari was not armed, he was preaching the word and healing a society wracked by conflicts and that is why we condemn the incident in the strongest terms possible," he said.
Similar sentiments were shared by sisters and priests from Sengera Parish where the late cleric was laid on hands before he set off in the missionary work.
On Thursday, his father said Fr Omboto had recently returned home to renew his passports before he went back to Cameroon only to meet his death months later.
He was a Mill Hill priest serving in the Diocese of Mamfe.
Fr Ondari was ordained in Kisii alongside two other priests and appointed to the Diocese of Mamfe, according to the St Joseph Missionary Society.
Fr Ondari's death has shone the light on the rising number of religious leaders killed amid a conflict that has lasted two-years and gripped the two English-speaking regions of Cameroon.
The priest had been working with people displaced by the conflict.
