It should be noted that Rotich trains among a small group of Kenyan runners in Santa Fe, NM. One man in this group, Joseph Mutinda, was just busted for doping. Rotich trains under the coach Ryan Bolton as do most (all?) the Kenyans in Santa Fe. Is Bolton also the coach of Mutinda? That is a question which the journalists among us should investigate.
The following is taken from a news brief on the USADA site:
"March 25, 2015.
USADA announced today that Joseph Mutinda, a Kenyan athlete in the sport of track & field, who has trained in Santa Fe, N.M. for the past several years, has admitted to the use of various prohibited substances and accepted a three-year sanction for his doping offenses."
