A Sudbury woman is renewing her fight for change, following a violent incident at a Toronto nursing home last week.

Last Wednesday a resident at a long-term care home in Toronto was charged with killing another resident and putting a second in hospital.

A similar incident happened in Sudbury in 2007.

Keith Croteau, 59, was beaten to death by his roommate while living in a long-term care facility in the city.

His sister Sandra wrote dozens of letters to her MP and MPP's after her brother's death in 2007, asking for more staff to be hired at long term care facilities — but to no avail.

The recent incident in Toronto horrified her, she said.

"That's when I thought 'no, nothing's been changed.' The people that they interviewed on the street [all said] the same thing: no staff ... Nothing has changed and it just really brought it all back."

Croteau said she is going to resume her letter writing campaign — this time petitioning new Ontario premier Kathleen Wynne.

The vice president with the Ontario Nursing Association, the union that represents many long-term care home workers in the province, said there continues to be violent incidents in nursing homes, and changes must be made.

Karen Bertrand said "discussing appropriate and approved pre-admission assessments" is key so that residents "who pose a risk or a tendency towards aggression [are] dealt with appropriately before they're admitted to a long-term care facility."

Bertrand said long-term care homes should also focus on training and hiring more staff — something Sandra Croteau says could have saved her brother's life.

Croteau said she will resume writing letters to MPPs to discuss her brother's case.

Croteau said she'd like to see more staff and, "since the institutions for psychatric and developmentally handicap[ped] are all shutting down, separate the senior citizens and have trained people taking care of them."
