  Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet
invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data,
which has generated considerable interest. We offer a possible explanation of
this observation in the general framework of MSSM with R-parity violation
through resonance production of tau sneutrino decaying into the LSP stau_1 and
W boson. We also give the predictions of this scenario for the LHC operating at
7 TeV center of mass energy.
