  Three nucleon short range correlations~(SRCs) are one of the most elusive
structures in nuclei. Their observation and the subsequent study of their
internal makeup will have a significant impact on our understanding of the
dynamics of super-dense nuclear matter which exists at the cores of neutron
stars. We discuss the kinematic conditions and observables that are most
favorable for probing 3N-SRCs in inclusive electro-nuclear processes and make a
prediction for a quadratic dependence of the probabilities of finding a nucleon
in 2N- and 3N- SRCs. We demonstrate that this prediction is consistent with the
limited high energy experimental data available, suggesting that we have
observed, for the first time, 3N-SRCs in electro-nuclear processes. Our
analysis enables us to extract $a_3(A,Z)$, the probability of finding 3N-SRCs
in nuclei relative to the A=3 system.
