Racing NSW chief steward Ray Murrihy will review the evidence from the Midsummer Sun cobalt inquiry in the next week but it appears certain  there will be further charges.

Suspended trainer Sam Kavanagh is facing eight charges from Midsummer Sun and race-day treatments of two other horses, but he has not been asked to respond to them as yet.

“It would be fair to say we have a multifaceted inquiry into the Midsummer Sun’s positive swab. The source of the bottle was of certainly the point of interest in the inquiry [on Tuesday],” Murrihy said.  “The inquiry has several branches but the who, how, when and why factors of the source [of the bottle] is very important in the case. We have more than just the analyst findings.
