The family of a man who died following an incident at a care home is demanding answers.

Police said it's alleged Frank Alexander, 87, was assaulted, fell backwards and hit his head on the floor at a care home on March 24.

Joe McLeod, a 70-year-old man with Alzheimer's disease, was charged on March 25 with aggravated assault.

Alexander was rushed to hospital in critical condition following the incident, but died Monday night.

His relatives want an inquiry into the incident.

Alexander's family wants to know who made the decision to place the accused in the care home.

Relatives moved Alexander, who also had Alzheimer's, into the Parkview Place care home less than three months ago. They thought he'd be safe there.

Frank Alexander's son Michael spoke out at a press conference on Thursday afternoon.

"We had no idea in his new home, he would be exposed to, and fall victim to someone known in the justice system," said Michael Alexander.

The Crown is now looking at the possibility of upgrading charges against McLeod.

Last fall, McLeod was held for five weeks in the Winnipeg Remand Centre after shoving his wife. The story drew attention as his family, alongside Jon Gerrard, provincial Liberal leader, called for McLeod to be moved from custody and into care.

"We cannot understand the insanity of deliberately moving an individual from the remand centre (accused) for an alleged violent crime and into the open halls and corridors of a nursing home full of the defenceless," said Michael Alexander.

Charges against McLeod for the incident last fall were stayed in November.

The province said McLeod was properly assessed and the decision to move him to a care home was not a knee-jerk reaction to political pressure.

Michael Alexander still worries political interference played a role and also points towards a press conference held following the March 24 incident and shortly before his father died.

"We are at home dealing with this. My dad's clinging to life and we see the (provincial) Liberal party doing a press conference. It was hard to take," he said.

The provincial Liberal party said the issue was too compelling not to get involved and it meant no disrespect. Party officials said holding a media conference at their office was meant to make things easier on the McLeod family as they offered a public apology.

Frank Alexander died in hospital days after allegedly being pushed.

"He hung on for five days because he was so strong, but we knew there was no hope," said Michael Alexander. Alexander, a war veteran, had served in the navy.

The McLeod family wasn't available for comment Thursday.

The Alexander family said it doesn't blame McLeod, but still wants a public inquiry. The family has also hired a lawyer.

"We want to see a solution. We do not want my father's death to be in vain," said Michael Alexander.

A funeral for Frank Alexander is scheduled for Saturday with all 14 of his grandchildren slated to act as pallbearers.
