James and Jennifer Crumbley's motion to amend their bond was denied by a judge on Friday. Both are charged with four counts of involuntary manslaughter in a Michigan school shooting. Their 15-year-old son, Ethan Crumbley, is charged with the shooting and killing of four classmates at Oxford High School.
District Court Judge Julie Nicholson denied the request, citing their ties to Florida, the seriousness of the crimes and their failure to turn themselves in when they were charged.

ABC News has reached out to James and Jennifer Crumbley's lawyers for comment. Prosecutors allege the parents gave their son a gun that was later used in the school shooting.
The parents hid in an abandoned warehouse in Detroit and had concealed their car by hiding their license plates instead of turning themselves in the day they were charged, prosecutors allege.
The couple put their house on the market, drained their son's bank account and asked family members to sell their horses, according to prosecutors.
