Idaho murders: Police 'want more than an arrest' in month-old quadruple murder mystery

'We want a conviction,' Moscow Police Department Cpt. Roger Lanier said Monday

Idaho police say they want "more than an arrest" in the nearly month-long-old, unsolved quadruple murder of four students near the University of Idaho campus on Nov. 13.

Moscow authorities are still working to determine who killed the four college students – Ethan Chapin, 20; Xana Kernodle, 20; Kaylee Goncalves, 21; and Madison Mogen, 21 – while they were sleeping in their off-campus home between 3 a.m. and 4 a.m. on Nov. 13, a Sunday. 

The Moscow Police Department (MPD) is "keeping investigation details safe" and not releasing certain information to the public so as not to tip off the killer," Robbie Johnson, the public information officer currently representing MPD, told Fox News Digital.

"It is what we must do to preserve the integrity of the investigation," Johnson added. "We want more than an arrest. We want justice. It takes time to do it right."

Lanier said analysts "have spent hours sorting through and trying to come up with the most relevant tips. First for the investigators to follow up on."

"They have re-interviewed some of the folks we've interviewed earlier in this investigation to clarify information. Sometimes when new information comes forward, the people that we've spoken to beforehand may have new insight on that," the police captain said. "So, it does often seem like we're backtracking, but we're really just trying to get the most important details and the best timeline that we can come up with."
