During the Hadley's Hope colonists' last and futile stand against the Xenomorphs, Newt lost Casey's body while escaping through the air ducts with her family, leaving only Casey's head. After Newt lost her family to the Xenomorphs, Casey became her only companion until the arrival of the Marines sent to investigate the situation on-world. In the sewers of Hadley's Hope, Newt dropped Casey's head when she was captured by a Soldier and it was the only thing Ellen Ripley and Corporal Dwayne Hicks found when Hicks finished cutting a grate leading to the sewers. The head then began to sink into the water as more Xenomorphs forced Ripley and Cpl. Hicks to leave. Casey's head was left behind when Lance Bishop, Hicks, Ripley and Newt fled the planet when the Atmosphere Processor exploded.
- Casey's head can be found in the sewers of Hadley's Hope in Aliens: Colonial Marines and discovering it will unlock the trophy/achievement "Mostly Come at Night...".
- To promote Aliens: Colonial Marines, Casey doll heads were sent to numerous people.
