information. understandably. because this is still very early on in the investigation. he said that they are working with a medical examiner office. to identify those who died. from this incident earlier today. at this holiday parade. when an suv just plowed through and struck more than 20 people. and again, he said there are multiple fatalities. chief, we also know that there's a person of interest who is in custody. what do you want to know at this hour? >> i'm sure they're in the process of debriefing individuals they have in custody to see if they can come up with a motive. this person may or may not be speaking with the police. they may have gotten a lawyer. who knows at this point. it's a very sensitive part of the period of time in the investigation. because information is just beginning to come out. one thing i see that's a bit on the strange side. it may mean nothing.
