We adjust our previous model to treat three-electron escape dynamics in a strongly-driven linear triatomic molecule, HeH2+. To avoid autoionization, we employ criteria to switch on and off the Coulomb forces between electrons at appropriate times. We investigate triple and “frustrated’’ triple ionization and see that two pathways prevail as seen before in “frustrated’’ double ionization. Our results indicate that in triple and “frustrated’’ triple ionization, electronic correlation is weak. Moreover, we find that the fragmenting molecule can deviate from its initial linear configuration.
