Some gas stations are under the watchful eye of the Kentucky Attorney General's office.
Jack Conway's office has confirmed its investigation of gas prices, originally just in Louisville, has now been expanded statewide.
It will look at recent prices charged statewide, including Tuesday's sudden spike in prices that some analyst have linked to the possibility of Hurricane Ike hitting the Gulf coast. Prices went up Tuesday roughly 25 cents even though crude oil prices dropped.
The A.G.'s office has sent out nine subpoenas requesting information into the wholesale prices of gas in both the Louisville and statewide markets.
Those companies have 27 days to respond.
