Who were the first three people to die in "The Great Gatsby" and how did they die?

Of the principle characters, there are only three who die:
Myrtle Wilson, Jay Gatsby, and George Wilson.  Dan Cody, a character only mentioned by
Gatsby and briefly described, died years before the story takes place.  Myrtle Wilson is
killed when Daisy hits her with Jay Gatsby's car.  Myrtle thought that Tom was in the
ostentatious yellow car that he'd driven earlier in the day when he stopped at Wilson's
gas station.  She ran out into the road in a desperate attempt apparently to get him to
stop.  Daisy was driving Jay's car, with Jay as a passenger, on their way back from the
explosive afternoon in New York City where all the secrets came out in a dramatic
confrontation between Jay and Tom and Tom and Daisy.  Daisy, in her frazzled state of
mind, probably didn't see Myrtle, but she knew she'd hit someone and drove off anyway. 
Georgie Wilson, with Tom's help, figured out that the car that hit and killed his wife
belonged to Jay Gatsby.  In his grief and with the help of Tom's misdirection, George
believed that Jay was the one Myrtle was seeing and that Jay hit and killed Myrtle on
purpose.  George shot Jay Gatsby, then turned the gun on himself and committed
suicide.
