New details in the Mollie Tibbetts case indicate that she was 
stabbed to death, and new details reveal that it's possible the 
suspect's girlfriend knew Tibbetts.

Mollie Tibbetts died from "multiple sharp force injuries," 
according to a preliminary autopsy report released by the Iowa 
State Medical Examiner Thursday. This would indicate she died 
after being stabbed, ABC News reports.

Tibbetts' death was officially ruled a homicide, and Cristhian 
Bahena Rivera has been charged with first-degree murder.

New details continue to come to light in the case. Tibbetts 
attended the same high school as the suspect's girlfriend, Iris 
Monarrez, ABC News learned on Friday morning. It appears the two 
were friends on Facebook, but investigators stated that this 
does not mean they were personally acquainted. Because Brooklyn, 
Iowa, is such a small town, they may have connected simply 
because they went to the same school.

Earlier this week, investigators said they were uncertain how 
Tibbetts was killed or whether she was sexually assaulted. 
They've made no mention of recovering a weapon linked to the 
death.

The examiner did not release additional details about the 
injuries Tibbetts suffered or what caused them, but said further 
examination of her body may result in additional findings. 
Autopsy reports are confidential under Iowa law, except for the 
cause and manner of death.

Tibbetts was last seen July 18 in Brooklyn, a rural town of 
about 1,400 people, as she took a routine evening jog. It's 
unclear whether she returned to the home where she was dog-
sitting for her boyfriend and her boyfriend's brother, who have 
said they were both out of town. She was reported missing by her 
family the next day after she didn't show up for work at a day 
camp for children.

Her funeral will be held Sunday afternoon in Brooklyn, Iowa.
