Fracture functions describe the production of hadrons in the target remnant region. Similar to both fragmentation and structure functions, these non-perturbative objects are measurable, universal functions that can be extracted from experiment in one kinematic regime and used to compute reactions at different scales, factorizing and evolving in a predictable way. The Jefferson Lab CLAS EG2 data-set, which measured high statistics 5-GeV electron-scattering data binned in variables such as $Q^2$, $x_B$ and $\nu$, offers a rich opportunity to extract fracture functions using electron triggered processes. This talk will describe the ongoing work to extract fracture functions from the $\Lambda^0$ yields identified in binned EG2 data. This work is supported in part by the US DOE contracts # DE-AC02-06CH11357 and DE-FG02-03ER41528 On behalf of the CLAS Collaboration
