The teenager, from Birchwood in Warrington, Cheshire, was found by members of the public as she lay wounded on a path in Linear Park, Culcheth, at around 3.13pm on Saturday.
Cheshire Police previously said there was no evidence to suggest Brianna, who was a transgender girl, was the victim of a hate crime.
But yesterday, the force issued a statement which said all lines of inquiry were being explored, "including whether this was a hate crime".
A boy and a girl, both aged 15, were arrested on suspicion of Brianna's murder and detectives have been granted an extension of 30 hours to further question the two suspects, police said.
