The bag contained 9mm ammunition like the one type used during the shootings.
One big development today in the investigation into Saturday's mass shooting: NPR's Dina Temple Raston has confirmed that investigators have located a black diaper bag with ammunition in it.
In a statement, the Pima County Sheriff's Department said the diaper bag resembled a backpack and contained 9mm ammunition consistent with the caliber of the weapon used in the shootings.
CNN reports the bag was found this morning by a teenager walking his dog. It was found near the neighborhood where shooting suspect Jared Loughner's parents live.
Investigators had been looking for the bag since the father of suspect Jared Loughner told deputies that his son fled with it, hours before Saturday's shooting at a Safeway just north of town.
Also, today, Pima Community College released 51 pages of documents from their public safety deparment pertaining to Loughner. Here's a brief description of some of the incidents:
-- Feb. 2010: A professor feels a confrontation with Loughner might "become physical." Loughner was upset because he had received a "B' in an assignment.
-- Sept. 2010: A professor calls campus police because Loughner "had caused a disruption in class." The professor told Loughner he would only receive partial credit for an assignment turned in late. Loughner argued that violated his "freedom of speech." The officer writing the report said Loughner could not verbalize what the problem was and his eyes were "jittery" and his head "constantly tilted to the left." The officer also noted that "there might be a mental health concern involved with Loughner."
-- Sept. 2010: Campus police look into strange YouTube videos. One of them, made by Loughner, alleged students were being tortured at the college. "This is genocide in America," he said in another.
-- Sept. 2010: Officers served Loughner with a "Notice of Immediate Suspension." As the officers read the letter aloud, Loughner "held a constant trance of staring." When they were done after one hour, Loughner said, "I realize now that this is all a scam."
