The writer errs in assuming that because someone was interviewed who resembles a person on a surveillance tape it means that the police believe the killer to look like that particular person who was interviewed. The more likely explanation is that police, having a surveillance tape taken near the site of the shooting, were trying to find everyone on it to interview for more information about what they saw in that location around that time in the hopes of turning up some additional information.
