(1960) The allowance of an amendment to a robbery information after close of state's case to charge that the amount taken from individual was $55 instead of $193 held proper where evidence showed that amount. State v. Clark (Mo.), 331 S.W.2d 588.
(1971) Amendment of information during trial in burglary prosecution to allege offense occurred between 11 p.m., March 31, 1970, and 12:35 a.m., April 1, 1970, instead of on April 1, 1970, held within judge's discretion. State v. Fowler (Mo.), 473 S.W.2d 353.
(1971) Defendant is not entitled to be released simply because the required number of terms have elapsed. He must show that he has demanded a trial and that such request was made without success for a reasonable length of time before his right to release is asserted. Failure to take affirmative action seeking speedy trial constitutes a waiver of that right and thus defendant's motion for discharge was correctly overruled. State v. Harper (Mo.), 473 S.W.2d 419.
