The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work.

“The lawyer also has a substantial and important role to perform in raising mitigating factors both to the prosecutor initially and to the court at sentencing. This cannot effectively be done on the basis of broad general emotional appeals or on the strength of statements made to the lawyer by the defendant. Information concerning the defendant’s background, education, employment record, ... relationships, and the like, will be relevant, as will mitigating circumstances surrounding the commission of the offense itself. Investigation is essential to fulfilment of these functions.”
2 later decisions quote this exact passage · from the concurrencee.g. Brimmer v. State · Adkins v. State“The resulting prejudice is clear. The only testimony the jury heard at sentencing concerning appellant’s mental history and condition, including the bizarre behavior he occasionally exhibited, was that presented by his mother. As her testimony makes clear, many others could have testified concerning his behavior, the fact that others did not do so undoubtedly diminished the impact on the jury of the facts she described.”
1 later decision quote this exact passage · from the concurrencee.g. Goad v. State“When the record shows a substantial deficiency in investigation, the normal deference afforded trial counsel's strategies is particularly inappropriate... . [This] Court will not credit a strategic choice by counsel when counsel `did not even know what evidence was available.'”
