SPRINGFIELD -- The investigation of two high-profile crimes in Greene County crimes is on hold as investigators wait for evidence to come back from the state crime lab in Jefferson City.  Sheriff’s department investigators say they've sent key evidence about the murder of Roland Comstock and the rape of a woman on Farm Road 80.  Now it's a waiting game.

  Someone shot Comstock, an attorney in Springfield and former state representative, in his home near McDaniel Lake north of Springfield on July 3.  A man raped the woman in her backyard on July 6.  Investigators hunted for the rapist all day but made no arrest.

  Detectives say they need results from evidence collected in both cases in order to focus in on a suspect.  The Comstock case has several things waiting to be tested.

  "There was one specific thing that we sent up there that could be tested basically in the same day, if you call up and request it.  Other things such as DNA and ballistics, you really can't put a rush on; you just hope that they get to it as soon as they can,” said Chief Deputy Jim Arnott.

  Arnott says evidence has to compete for lab time with cases from around the state, including Kansas City and St. Louis.  Right now the average time to get back a DNA test is one year.
