A jury convicted an Austin man in the 2015 murder of a 75-year-old grandfather, who was found dead in a Northwest Austin garage.

After the week-long trial for Irwin Pentland, in the 427th District Court, he was sentenced to life without parole, according to the Austin American-Statesman.

The prosecution argued that Pentland killed former IBM executive Phillip Liberty, 75, and stole thousands of dollars from him with forged checks, the Statesman reported.

Prosecutors reminded jurors that before Pentland was considered a suspect in Liberty's murder, he was arrested for endangering Liberty's 2-year-old grandson on Dec. 2, 2015. The prosecution also highlighted Pentland's previous criminal record, which included felony robbery.

According to the Statesman, Pentland's defense attorney argued that his prior criminal record and actions with the victim's grandson had nothing to do with the case, instead shifting jurors back to the lack of a witness, murder weapon and confession.
