Gabby Petito homicide: Utah officers may not have had all information responding to Moab incident, experts say

With the City of Moab in Utah announcing an investigation into the police handling of an Aug. 12 domestic dispute involving Gabby Petito and Brian Laundrie, experts say the officers may have acted appropriately — based on incomplete information.

Under Utah law, police are required to either arrest the suspect or issue a citation in a domestic violence situation. They have no discretion in the matter, she said.

"The statute’s clear because it says ‘shall,’" Gustin said. "And that’s very important because when it says ‘shall’ in a statute, it means they have to do it."
