Allemann had lost interest and quit while Kocher's exit was due to internal strife following the band's show at Salle des Spectacles in Servion, Vaud which was filmed for broadcast on Télévision Suisse Romande (TSR).
Meanwhile, Killer founding members Many Maurer and Beat Kofmehl joined forces with Witchcraft/Blood Six vocalist Peter Tanner and drummer Greg Bleuel under the name Headhunter, which resulted in the band's eponymous 1985 release, produced by then former Krokus bassist Chris von Rohr.
[5] Beat, now Brian, Kofmehl would replace the Gotthard bound Marc Lynn in the band China in time to record their Stephan Galfas produced 1989 sophomore album, Sign in the Sky.
Kocher would resurrect Killer several times in the 2000s with different personnel - including a one-off all original members reunion on April 27, 2002, in their hometown of Solothurn - but disbanded it in 2012 out of frustration over poor concert attendances and lack of progress on a new album as well as persistent health problems.
As of 2016, Killer, led by Kocher and vocalist Andy Lickford, was active again and released a 4-song EP, Pure Dynamite, which includes the 1981 band classic, "Crystal Butterfly", as a CD bonus track.
On May 25, 2019, the current Killer line-up comprising Crown Kocher, lead vocalist Patrick Strobel, guitarist Peter Berger, bassist Mirko Buccio, and drummer Roberto Antonucci released Screamgunn, the group's first new album since 1986's Young Blood.
[9] In 2018, Kocher released the single "Let Me Take You In My Arms" under the project name Crown, also featuring Killer bassist Mirko Buccio, Kaktus drummer Duco Aeschbach, and vocalist Jean-Marc Viller whose credits include Swiss acts Big Red One, Neverland, and Daydreamer.
