In January 2024, the Football Association opened a formal investigation into her death after reports of wrongdoing by her club manager.

Cusack attended the University of Derby where she achieved a first-class honours degree in marketing, public relations, and advertising.

[12][13][14] Eighteen months later, she renewed her contract with the club,[13] and subsequently became the first player to reach 100 appearances for Sheffield United.

[19] Cusack was called up for England U19 during the 2013 UEFA Championship qualifying round,[20] but she was not named in the squad for the final tournament.

Wreaths were laid outside Bramall Lane by supporters and Newcastle co-owner, Amanda Staveley, and on the pitch by Cusack's family, club captain Sophie Brown and former player Tony Currie.

[26] On 19 December, it was reported that the inquiry, led by retired detective superintendent Dennis Shotton, found no evidence of wrongdoing at Sheffield United.
