Zina Daniel’s family believes that GPS monitoring on domestic violence abusers could have saved her life.

Days after hairstylist Zina Daniel Haughton obtained a four-year restraining order against her husband she planned to divorce, he stormed into the upscale Azana, killing her and two of her co-workers and wounding four others before killing himself.

Elvin Daniel, Zina’s brother, has been pushing for use of a GPS monitoring device that would alert a domestic violence victim when the abuser is nearby or is about to violate the restraining order, reported Patch media partner WISN. 

Gov. Scott Walker has included the $3 million proposal as part of his budget, which needs to be reviewed by lawmakers.
