A 90-year-old man with dementia has been ruled unfit to stand trial after being accused of killing his wife in their Bukit Panjang flat. The High Court determined that the man, who suffers from the condition, cannot understand the charges against him. As a result, the court set a notional imprisonment term of five years. The case, which has raised questions about legal responsibility and mental capacity, is now under review by legal authorities. The wife’s death remains under investigation, with no official cause of death confirmed. Authorities are considering the next steps in the case, including whether the man should be placed under supervision or receive further medical care. The decision highlights the complexities of prosecuting individuals with cognitive impairments.
