A Wells Fargo boss, Willis Ayieko, was murdered last week while investigating a Sh94 million heist linked to a security firm, raising concerns about his death's connection to the investigation.

• Ayieko's body was found on October 23, three days after he went missing.
• He played a key role as the director of human resources in the internal inquiry related to the heist.
• No arrests have been made in Ayieko's murder, although he was last seen at a condolence visit for a friend and was well-regarded in his community.
