Make elder abuse a specific criminal offence

My elderly vulnerable loved one now suffers major psychological problems due to the abuse she has endured, which in turn, has resulted in not being able to prosecute the offender(s). We both think a tighter law could act as a deterrent. Trusting family above and beyond, but even loved ones can abuse their position of trust. Abusers know there is little chance of prosecution, and unfortunately this type of crime is disturbingly common. Our elderly need a shield.
