Rabbi Eitam Henkin H"yd who was killed recently by an Arab, was not only a quiet, unassuming, modest and humble individual, but was also a serious talmid chochom, a rising star who had a great future ahead of him. He was already a prolific author and had so much more to contribute.
Here is a link to his blog.
יהי זכרו ברוך, ולא נדע עוד שוד ושבר בארצנו, ומחה ה' אלקים דמעה מעל כל פנים, ויקיצו וירננו שוכני עפר בתחיית המתים אמן ואמן
