Horgen, a woman in her 50s, was found dead last week in the Reihan Forest, close to her home in the settlement of Tal Menashe, from where she had gone out for a jog.
Her body was found on the side of a path in the forest and showed signs of violence, including to her head. Her family reported her missing on Sunday. She is survived by her husband, Benyamin, and six children. Her youngest child celebrated his bar mitzvah three months ago.
The suspect was arrested in a joint operation by the Police, the IDF and the Border Police on Thursday.
He is a 40-year-old Palestinian who has had previous involvement in security-related activity. His political affiliation isn’t clear.
On Thursday at around noon, intelligence units found that the suspect was staying at his mother’s house in the village of Toura.
The Yamam then arrived at the scene. With assistance from intelligence drones, the suspect was located on a rooftop and was later apprehended. He was taken in for questioning by the Shin Bet (Israel Security Agency).
The Paratroopers Special Unit came to the scene after the arrest and detained family members and other suspected accomplices.
Before the attack on Tuesday, the suspect crossed the security barrier in the northern West Bank.
