We consider the pair production of color triplet spin-$3/2$ quarks and their subsequent decays at the LHC. This particle, if produced, will most likely decay into top quark and gluon, bottom quark and gluon, or a light quark jet and gluon, depending on the quantum number of the spin-$3/2$ particle. This would lead to signals with $t\overline{t}jj$, $b\overline{b}jj$, or $4j$ in the final states. We present a detailed analysis of the signals and backgrounds at $\sqrt{s}=7$, 8, and 14 TeV and show the reach for such particles by solving for observable mass values for the spin-$3/2$ quarks through its decay products.
