"I don't think they're moving fast enough. I think it is too big for the Fargo Police Department," said Norberta LaFontaine-Greywind, adding that authorities had searched the Red River using dogs and had also conducted searches using a helicopter.
Amanda Viver, spiritual director of the Native American Christian Ministry, called on the public to place pressure on police to encourage more resources be put into the search, including asking the FBI for help.
"There has to be justice. We have to know where she is," said Viver, who suggested people show up at the police station to make their desires known.
Fargo Police Chief David Todd said Wednesday afternoon the search for Savanna "is our No. 1 priority. All of our resources have been focused on this since the beginning."
