Eleven people were arrested in the Lower Galilee city of Afula early Sunday, after a protest calling for justice for the killing of a local teen turned violent.

An estimated 2,500 people gathered in the city Saturday night to call for the government to hand down more severe sentences to murderers, including those who killed Shelley Dadon, and to stop the early release of terrorists.

Dadon, 19, was found dead in her car in the nearby town of Migdal Haemek earlier in the month.

Memorial candles were lit for Dadon and signs bearing the words “Shelly’s blood is my blood” were held aloft at the march.

Eleven people were arrested at the end of the march when they began throwing rocks and attempted to damage a vehicle, a northern district police spokesman told The Times of Israel. He said the suspects were mostly teenagers and said three of them, aged 16, 17 and 20, were to have an arrangement hearing on Sunday.

Police officials have said they believe the murder of Dadon was nationalistically motivated.

At the demonstration, protesters wore red gloves to highlight what they referred to as Israel’s lenient approach to those with “blood on their hands,” an expression in Hebrew used to mean those who have committed murder.

Public Security Minister Yitzhak Aharonovitch vowed during a condolence visit on Monday to the woman’s family that the perpetrators of the murder would soon be found.

Dadon’s battered body was found on May 1 in an abandoned parking lot in Migdal Ha’emek, a city a few miles north of her hometown of Afula.

Details of the investigation of her death are under a gag order.

While he couldn’t offer details due to the gag order, Aharonovitch said he believed the investigation was on the verge of dramatic developments.

“The investigation has made very great strides, which can only be described as dramatic,” Aharonovitch told the Dadon family. “The murderers will be arrested soon and will pay the price,” he vowed, calling the killing “one of the most despicable acts.”
