They arrested the patient and took him to the police station while the body was taken to Chiromo Mortuary.
Gigiri OCPD Vitalis Otieno said the patient would be held until investigations are complete.
He said statements by hospital staff showed that the patient mishandled his firearm.
Faustin’s widow, Doreen Akinyi, said he was shot in the left eye and his body had a large wound on the forehead.
“I cannot tell what happened,” said a distraught Akinyi.
“I just don’t know. The hospital sent some staff to my house at 3am and they told me that a patient had shot my husband as he was admitting him.
“They said the patient had refused to surrender his gun but my husband managed to sweet-talk him to do so but when the patient was removing the bullets from it, he shot my husband.
“I do not understand this story; I just want the police to investigate and justice be served.”
Akinyi said she had called the father of her three children at around midnight to check up on him because he was supposed to have arrived home but he did not pick up her calls.
“When he failed to respond, I went to bed but I was worried about him even before his colleagues came home and broke the news,” said Akinyi at the mortuary, where she had gone to identify the body.
TOO MANY QUESTIONS
Mr Christopher Gisiri, a friend of Mwadilo’s, asked why the hospital allowed someone, and a psychiatric patient as such, to get into the hospital with a gun, knowing its danger.
“I do not even understand why, in the first place, the government licensed the gun to him,” Mr Gisiri said. “There are just too many questions.”
The Nation could not get a comment from the hospital’s management as the administrator was not in. Several calls to his private line went unanswered.
Section 5 of the Firearms Act requires that a firearm certificate be granted by the licensing officer only if satisfied that the applicant has a good reason for purchasing, acquiring or having the firearm or ammunition without danger to the public safety or to the peace.
