From The Modesto Bee:
The decision to turn over the investigation was made after â€œnew informationâ€ about Faisal Mohammad came to light Saturday, Warnke said Monday. He declined to elaborate.
â€œIâ€™m not at liberty to discuss the information, but the developments on Saturday caused us to turn that over to (UC Merced) and the FBI will assist them,â€ Warnke said. A law enforcement official, who spoke to the Sun-Star on condition of anonymity, said the information included questions about the manner in which Mohammad was dressed during the Nov. 4 attack and the types of websites he may have visited in the weeks and days before. Additionally, the official said, investigators found a printout of an image of an Islamic State flag among Mohammadâ€™s belongings.
The significance of the items, and any possible connection to the attack, is unclear and remains under investigation, the official said.
