Kenyan gospel singer Ruth Matete on Tuesday morning presented herself at the Directorate of Criminal Investigations to record a statement following the death of her husband.
She has been accompanied by her lawyer.
Last week, Ruth confirmed the news of her Nigerian husband's death via social media.
"My Husband Beloved John Apewajoye has gone to be with the Lord ..I humbly ask for your prayers during this difficult time,' she wrote on Facebook.
Pastor John passed away on Saturday while receiving treatment at a local hospital.
He succumbed to injuries after he was burnt while in the kitchen a few minutes after fixing a gas cylinder.
Matete's friend and YouTuber Milly Chebby later gave an account of the incident.
"Last week on Monday, Ruth and her husband John changed their gas cylinder and when they got to the house, he went to the kitchen to fix it. he noticed it was excess and he took the cylinder to the balcony and tried releasing some so that it would be okay to use," Chebby said.
