Hundreds of police officers and others gathered in a basketball arena to honor slain Terre Haute Officer Brent Long. The line of mourners moved slowly through Indiana State University’s Hulman Center to pass by Long’s flag-draped casket during the six-hour visitation period Sunday ahead of Monday’s funeral at the arena. Long and his police dog Shadow were shot a week ago while serving an arrest warrant at a Terre Haute apartment. Shadow was released from a veterinary hospital Thursday and participated in Sunday’s ceremonies. Long, 34, leaves behind a wife, an 11-year-old daughter and a 10-month-old son. Seven people have been arrested in connection with his death. Shaun Seeley, the man being served the warrant, also died in the shootout.
