History: 1959 act required report of probation officer's investigation prior to sentencing if defendant's record discloses a conviction obtained prior to three years from present conviction; P.A. 76-336 substituted references to capital felony for references to first degree murder where appearing; P.A. 78-188 required that criminal records be furnished to restitution specialists upon their request; P.A. 80-313 divided section into Subsecs. and substituted “may” for “shall” in provision re required reports of probation officer in Subsec. (a); Sec. 54-109 transferred to Sec. 54-91a in 1981; P.A. 82-281 amended Subsec. (a)(2) to increase from three to five years the period of time between convictions, and inserted a new Subsec. (b) authorizing certain defendants to waive the investigation, relettering former Subsec. (b) accordingly; P.A. 82-298 deleted references to restitution specialists in newly relettered Subsec. (c); P.A. 85-98 amended Subsec. (c) by adding provision requiring the investigation to include an inquiry into any damages suffered by the victim; P.A. 90-261 amended Subsec. (c) by adding provision requiring the investigation to include an inquiry into whether the department of correction recommends that the defendant participate in a special alternative incarceration program; P.A. 95-225 and P.A. 95-261 both added substantially identical provisions as new Subsec. (d) authorizing the disclosure of information in the files or report of an investigation to the Office of the Bail Commission for the purpose of performing the duties in Sec. 54-63d (Revisor's note: P.A. 95-225 provided that “Any information contained in the files or report of an investigation made pursuant to this section may be disclosed to the Office of the Bail Commission ...”, whereas P.A. 95-261 provided that “Any information contained in the files or report of an investigation pursuant to this section shall be available to the Office of the Bail Commission ...”); P.A. 00-64 amended Subsec. (a) by making technical changes and deleting provision that required investigation if record of defendant, as shown by prosecutor, discloses conviction obtained prior to five years from guilty finding in present prosecution, and amended Subsec. (d) by adding provision making information contained in files or report available to Department of Mental Health and Addiction Services for purposes of diagnosis and treatment; P.A. 02-132 amended Subsec. (d) by replacing “Office of the Bail Commission” with “Court Support Services Division”; P.A. 03-48 amended Subsec. (c) to delete provision requiring investigation to include an inquiry into whether the Department of Correction recommends that the defendant participate in a special alternative incarceration program in accordance with Sec. 53a-39b, reflecting repeal of said Sec. by the same public act; P.A. 12-5 amended Subsec. (a) to add references to provisions of Sec. 53a-54b in effect prior to April 25, 2012, re capital felony and add references to murder with special circumstances under Sec. 53a-54b, effective April 25, 2012; P.A. 17-31 amended Subsecs.
