Police have searched the neighbor’s home three times. The police department has also conducted river and aerial searches with the help of border patrol official without success.
Her family and boyfriend have also canvassed the area and put up hundreds of “missing” flyers around town, but those efforts have produced no clues to her whereabouts. They have stopped actively searching, because, her mother said, there was no place left to search.
‘She’s in danger’
Savanna is 5-foot-4, with long brown hair, green eyes and tattoos on her right leg and foot. When she was last seen, she was wearing a pink shirt, shorts and Nike slip-on sandals.
“She’s in danger,” her mother said. “Something’s wrong.”
Savanna, a certified nursing assistant lived in an apartment at 2825 9th St. N. in Fargo with her mother, father and 16-year-old brother. She had moved to Fargo in January 2016 for her job. Other family members moved to the city a few months later.

Savanna’s mother reported her missing to Fargo police about 4:30 p.m. Saturday. Since then, Fargo police, aided by other law enforcement agencies, have searched extensively for the woman without success.
Fargo police conducted two K-9 searches. U.S. Customs and Border Protection did an aerial search. The Fargo Fire Department searched the Red River, and Savanna’s uncle did the same with a personal watercraft.
Police searched the upstairs neighbor’s apartment three times. They interviewed family members, friends, neighbors and her employer.
“At this time, there is nothing to suggest criminal activity,” Fargo Deputy Police Chief Joe Anderson said.
Savannah and her boyfriend, Ashton Matheny, were expecting a child, a daughter, in late September. They had signed a lease on an apartment in north Fargo and planned to move there on Sept. 1. She has no other children.
Savanna, a member of the Spirit Lake tribe, was born in Belcourt, N.D. Her father is a Spirit Lake member, while her mother is a member of the Turtle Mountain tribe.

Savanna LaFontaine-Greywind vanished without a trace, on Saturday after modeling for an upstairs neighbor in this northside apartment building in Fargo, ND

On Saturday, a woman living in a third-floor apartment knocked on their door and asked Savanna if she would act as a model so she could pin a dress she was sewing. She offered to pay her $20. Savanna agreed.
The family didn’t know the woman well, and her mother was wary of her because of previous experiences.
Savanna texted her mom to inform her that she was going upstairs to help the neighbor. She also texted her boyfriend about the same time. “We were joking around,” he said.
“We didn’t think too much about it,” her mother said.
Savanna was supposed to give her brother a ride to work shortly before 3 p.m. on Saturday. Her mother sent the brother upstairs about 2:30 p.m. to get Savanna, but nobody answered the door when he knocked. Then Savanna’s father, Joe Greywind, went upstairs and knocked on the door. The woman who lives there answered, and she told him they weren’t finished working on the dress.
Since Savanna wasn’t available, her mother gave her son a ride to work. She assumed when she returned home that Savanna would be in her room. When she discovered she wasn’t, she panicked, ran upstairs, knocked on the door and was told her daughter had left.
“I repeatedly called her, texted her,” she said. “I got no reply, no response, no answer.”
Savanna’s mother said it would be out of character for her to go anywhere by herself on foot because she was cautious, and would get upset when her sister walked by herself anywhere. She said it is also “very” out of character for her not to respond to texts or phone calls.
“My daughter is always on Facebook, always texting,” she said. Savanna had posted or shared posts on Facebook four times on Saturday morning.
Savanna’s mother said Savanna had no history of mental issues and has never disappeared before.
