joining me now, mark potter, who has been following this story for us. mark, let's talk about this person of interest. what do we know about him and what authorities are saying? >> what we know is that he is an instructor of geography and social science education, currently employed at the university. and that he got all three of his degrees, bachelor's, master's and a ph.d. just this spring at the university, at delta state. the police say they do not believe that he is on the campus now. but they're taking no chances. they're searching everywhere on the campus but say they don't think he's there. they're asking the public to call in any tips they might have to local law enforcement officials. the victim, ethan schmidt, as you say, professor of american history, got his ph.d. at the university of kansas. teaches all levels of american history and was considered beloved. many people have spoken so kindly about him since his death, and his death is being mourned by faculty and students at the university. police are also saying that they're looking into the

mark potter is in south carolina. what's expected to happen at this hearing later today?determine whether the former officer, michael slager, gets out on bond or remains in jail until his trial. the question to be answered by the judge is whether he is a flight risk or a danger to the community. now, his attorney says he is neither a risk nor a danger. he also argues that he is also not guilty of murder as charged in the shooting death of walter scott which we all saw on that cell phone video. the attorney argues that before that video was shot, moments before, seconds before that video was shown, there was actually a tussle on the ground as the officer tried to arrest scott. they got in a tussle and he says scott actually grabbed the officer's taser and fired it twice. the defense is presenting fbi-enhanced video that it says actually shows that scuffle and at some point shows scott on top of the officer. now, in filings it also says that scott's dna is found on the taser, that he had trace elements of gunshot residue on his hands, trace elements of cocaine and alcohol i

mark potter joining us from charleston. bond hearings don't usually take quite this long. on? >> reporter: well, ari, it hasn't really been all that long given the controversial and emotional nature of the case. there was a hearing yesterday afternoon, there was a little bit of a follow-up hearing this morning and the judge only had the case for a few hours for his consideration. now, that judge clifton newman said that he will try to rule as expeditiously as possible. we are standing outside the courthouse awaiting the ruling although there's absolutely no guarantee that it could happen today. it could be another day. in court this morning, the former police officer the defendant told the defendant he is not a flight risk. he'll obey all the rules of the court should he wibe let out on bond and not a danger to the community and would like to be with his family an newborn son while awaiting the hearing. the prosecutor said he is a flight risk, a doing tore the community because of the serious charges against him and the very strong evidence against him. the victim's family

nbc's mark potter explains. >> reporter: at dawn, a team of agents from u.s.nd customs enforcement known as i.c.e. is on the streets in riverside, california, tracking an alleged gang member who's in the u.s. illegally. he's facing a weapons charge and was recently released on bond. i.c.e. had asked the local jail to transfer him to their custody for deportation, but the jail refused. so i.c.e. had to grab him during a risky manhunt. the best option for us in these type of cases is to take custody of the person when they're in jail, in a secure environment, behind those jail doors where he has no weapons. >> reporter: until last year, i.c.e. would routinely ask jails to hold outgoing prisoners at least two extra days so i.c.e. could pick them up. but federal courts ruled that delay. unconstitutional and hundreds of jails around the country began refusing thousands of i.c.e. requests anticipating lawsuits. >> the biggest concern is the liability it brings with these programs. >> reporter: to help address this problem, i.c.e. is now offering a compromise plan, a
