BEREAVED daughter of Martin Leffler, Hannah, has launched a campaign for tougher sentences in one-punch manslaughter cases.

West Cheshire College student Hannah Leffler, 19, has created a group on social networking website Facebook titled: ‘Justice for Martin Leffler and all other victims of one punch manslaughter.’

Within a week, the group already had more than 1,000 members and the Lefflers have received messages of support from several people who know friends and family who have suffered a similar fate to Mr Leffler.

Hannah's father's killer, Michael David Slack, 23, was sentenced to five years in prison earlier this month for killing Mr Leffler with a single punch outside the Old Red Lion Pub, Little Sutton in December 2008.

Hannah writes: “Although this will never bring Martin back, it is not justice and sentences this weak are nothing compared to the life long pain the families are left with.

“Many families go through this hurt and nothing is done about it except a flimsy jail sentence.

“It is too often that the victims are not receiving any sort of justice for their loved ones who they will never see again. So I have set up this group to gain support to try and get these sentences made tougher!”

She is also urging people to sign a petition to the Prime Minister demanding tougher sentences for cases of manslaughter using unlawful violence. It can be found at

Hannah adds: “The government wont listen to just one voice, but they may listen to many so please help!”

Sunday was Hannah's 19th birthday but the event was marred by the absence of her beloved father.

She wrote: “Wish you were here for my birthday today dad love you loads miss you soo much.”
