He said that the press " overlooked what we have been doing in our communities for many years ... We have been talking to our communities . We have been talking to our families . " Syed Rizwan Farook , one of the shooters in the 2015 San Bernardino attack , and neighbor Enrique Marquez , who is currently under investigation in relation to the attack , attended prayers at the Islamic Center of Riverside along with one of the victims of the shooting .
