A Florida teen, who along with her mother is accused of rigging a homecoming queen election in her favor, is being charged as an adult, Fox News has confirmed.  

Emily Rose Grover was still 17 when she was arrested in March and turned 18 last month. A spokesman for the State Attorney's Office in Escambia County told Fox News Tuesday that Grover will be tried as an adult.

Grover and her mother, Laura Rose Carroll, 50, face multiple felony charges stemming from the October homecoming vote at Tate High School in Pensacola, Florida.

While employed as an assistant principal at Bellview Elementary School in the same county, Carroll accessed the school district's internal system to cast fraudulent votes for her daughter, officials said.

Authorities began investigating the matter in November after the Escambia County School District reported unauthorized access into hundreds of student accounts, according to the Florida Department of Law Enforcement.

Investigators found that hundreds of votes for the school's homecoming court were flagged as fraudulent. More than 100 votes were from the same IP address within a short period of time, the investigation found.

Investigators then found evidence of unauthorized access to the system linked to Carroll's cellphone and computers at her home. There were nearly 250 votes cast for homecoming court from those devices.

Multiple Tate students reportedly told investigators that Grover described using her mother's system access, or of watching her mother access records, for years. Investigators learned that since August 2019, Carroll's account accessed 372 high school records – 339 of which were Tate students.

Officials have confirmed that Carroll was suspended from her job, but it wasn't immediately clear if she has been fired. Authorities said Grover was expelled from Tate High School.
