  In this study, we conduct a detailed analysis of the Ko\v{s}ice meteorite
fall (February 28, 2010), in order to derive a reliable law describing the mass
distribution among the recovered fragments. In total, 218 fragments of the
Ko\v{s}ice meteorite, with a total mass of 11.285 kg, were analyzed. Bimodal
Weibull, bimodal Grady and bimodal lognormal distributions are found to be the
most appropriate for describing the Ko\v{s}ice fragmentation process. Based on
the assumption of bimodal lognormal, bimodal Grady, bimodal sequential and
bimodal Weibull fragmentation distributions, we suggest that, prior to further
extensive fragmentation in the lower atmosphere, the Ko\v{s}ice meteoroid was
initially represented by two independent pieces with cumulative residual masses
of approximately 2 kg and 9 kg respectively. The smaller piece produced about 2
kg of multiple lightweight meteorite fragments with the mean around 12 g. The
larger one resulted in 9 kg of meteorite fragments, recovered on the ground,
including the two heaviest pieces of 2.374 kg and 2.167 kg with the mean around
140 g. Based on our investigations, we conclude that two to three larger
fragments of 500-1000g each should exist, but were either not recovered or not
reported by illegal meteorite hunters.
