(MCT) — CHICAGO — The reputed gang member accused of gunning down 15-year-old Hadiya Pendleton last month was on the street even though he had been arrested three separate times for break-ins and trespassing while on probation for a weapons conviction in recent months, the Chicago Tribune has learned.

In two of those arrests, including one just two months ago, Cook County, Ill., probation officials failed to notify prosecutors or the judge that Michael Ward had been arrested on the new misdemeanor charges and violated his probation.
