IDF troops on Monday raided the Yatta home of the terrorist who murdered Ari Fuld, 45, near the Gush Etzion Junction south of Jerusalem on Sunday.
The troops mapped the site ahead of its future demolition, a punitive measure aimed at generating deterrence often taken against the families of terrorists who murder Israelis.
The terrorist's mother said Sunday that she had told the Palestinian security forces as well as Israeli soldiers at a nearby checkpoint of her 17-year-old son's intentions as soon as she realized what he was going to do.
The attacker's father said his son had not been affiliated with any Palestinian terrorist group.
Hamas, the terrorist group that controls the Gaza Strip, and Islamic Jihad both lauded the attack on Monday, but neither claimed the teen as their operative.
An IDF official confirmed that the mother had informed soldiers at the Meitar checkpoint near Hebron of her concerns, and that the report of the stabbing attack came moments later.
Hundreds of people attended Fuld's funeral on Sunday night.
The U.S.-born father of four lived in the Gush Etzion community of Efrat and was a well-known pro-Israel advocate.
According to his Twitter account, he had planned a lecture tour in the United States in November.
Video footage from the scene showed Fuld managing to chase and fire at his assailant before collapsing. Other civilians also shot at the terrorist.
Fuld was rushed to Jerusalem's Shaare Zedek Medical Center, where he was pronounced dead.
The terrorist reportedly sustained moderate wounds and is in the Shin Bet security agency's custody.
Fuld was a well-known English-language internet commenter on current affairs and the weekly Torah reading. He was known for his hard-line nationalist ideology and strong support for the Israeli military.
Settler spokesman Josh Hasten said he had known Fuld for about a decade and that his friend traveled widely to showcase "the beauty and reality of life" in the country.
Fuld delivered care packages to Israeli soldiers and would go on solidarity trips to communities near the Gaza Strip during times of fighting with the Hamas militant group, Hasten said.
"When the rockets were falling, that's when he would get in his car and go down to Sderot," Hasten said.
Fuld was known for his outspoken manner, which included verbal clashes with Palestinians and critics of Israel that could land him in trouble. At times, his Facebook account was suspended.
"He did not hold back on his opinions," Hasten said. "If that meant 30 days of Facebook jail, so be it."
Prime Minister Benjamin Netanyahu lauded Fuld on Facebook for fighting his attacker "heroically" and remembered him as "an advocate for Israel who fought to spread the truth."
U.S. Ambassador to Israel David Friedman tweeted, "America grieves as one of its citizens was brutally murdered by a Palestinian terrorist. Ari Fuld was a passionate defender of Israel and an American patriot. He represented the best of both countries and will be deeply missed. May his family be comforted and his memory be blessed."
A Shin Bet statement said the agency had no intelligence indicating an imminent terrorist attack.
A military official said that while no additional troops were deployed on the ground at this time, concerns of copycat attacks have prompted the IDF to bolster its presence at major checkpoints and known flashpoints.
