Suspected serial killer and convicted murderer Billy Chemirmir has been found guilty of murdering another woman following a trial that lasted four days at the Frank Crowley Courts Building in Dallas on October 7.

The trial was Chemirmir’s third trial since being accused of murdering several elderly women in North Texas. So far, the 49-year-old has been indicted on 22 capital murder charges in Dallas and Collin Counties.

Prosecutors said Chemirmir killed the women and stole their jewelry and valuables. During the trial, lead prosecutor Glen Fitzmartin suggested to the jury that Chemirmir made killing and stealing his work.

“Billy Chemirmir turned these women’s lives into his objects of desire and greed and cast them away,” Fitzmartin said. “Billy Chemirmir is a capital murderer just as he set out to be.”

The Dallas County jury took less than 30 minutes to find Chemirmir guilty on Friday of murdering Mary Brooks, 87, in her Richardson home. As reported by The Dallas Express, Brooks was found dead in her Dallas condo in 2018.

Authorities initially ruled that she died of natural causes. However, police reopened the case when other women died under similar circumstances.

During the trial, prosecutors showed a surveillance video from a Walmart on Coit Road that showed Chemirmir in the vicinity before Brooks stepped in wearing the same clothes she had on when her body was discovered.

Another video showed a silver Nissan Altima, which prosecutors said was being driven by Chemirmir, parked next to the victim’s vehicle. The Nissan left moments after Brooks left the parking lot and followed her home.

Prosecutors presented cellphone data evidence that put the defendant in the vicinity of the Walmart at the same time and also at Brooks’ home for approximately 45 minutes.

Defense lawyers argued that prosecutors, or anyone at all, could not be certain that his client drove the Nissan as the make and model is too popular and could have been driven by anyone other than his client.

The defense also attempted to counter the cellphone data evidence by claiming that it could not say precisely where the defendant’s phone was and that it did not mean that he had his phone with him.

Contrary to Hayes’ argument, prosecutors showed a photo of a ring that Chemirmir had posted on a resale website. The ring looked like the one that the victim had owned.

Ann Brooks, Brooks’ daughter, told jurors that she and other family members began to notice her mother’s jewelry was missing shortly after she died.

Following the guilty verdict on Friday, Chemirmir was automatically sentenced to life imprisonment without the possibility of parole.

Dallas County District Attorney John Creuzot had declined to pursue the death penalty, as reported by The Dallas Express.

After the sentencing, Ann Brooks explained, “We are so thrilled that this defendant will never be able to hurt any other family again.”

Despite two convictions and multiple murder indictments, Chemirmir has denied all accusations. His lawyers have filed a notice to appeal the conviction.
