Stacy’s family said concerns for the “safety of people right now” have not been addressed.
Her relatives are backing a campaign calling for high-risk domestic abuse perpetrators or suspects released on bail to have their location monitored using GPS equipment.
This could include individually assessed exclusion zones around victim’s homes or workplaces, and alerts that trigger police responses when conditions are breached.
Scottish ministers have previously faced criticism over the slow rollout of Global Positioning System (GPS) equipment, which is used far less in Scotland than in some other countries.
Justice Secretary Neil Gray said tackling violence against women and girls is a “top priority” for the government and part of that was addressing attitudes and influences.
Speaking on Mornings, he said: “We’re taking steps at the moment to strengthen bail conditions and bail monitoring. We are looking to expand GPS technology, for instance.”
Gray said the technology is available and he is looking to accelerate a “full roll-out and availability across the board” of the technology.
When asked if he could to commit to a roll-out by the end of the year, Gray said he “would check”.
