The mother of a woman whose live-in boyfriend admitted killing her and two others within a four-year span has addressed her daughter’s killer in a Florida courtroom, telling him she hopes he “rots in hell.”

The victim’s mother, Jennifer Greene, said she had no room for mercy in her heart for Charles Andrew Martinez, 29, who admitted in a Tampa courtroom on Friday to killing her daughter, Lindsay Greene, and Greene’s friend Jennifer Kalb in 2013 by stabbing and beating them before setting a townhouse in Brandon on fire, the Tampa Bay Times reports.

“Charlie Martinez, there is no justice on this Earth for you,” Jennifer Greene told her daughter’s former boyfriend. “And I hope you rot in hell.”

But Kalb’s mother, Jacqueline Strecker, was more forgiving of her daughter’s admitted killer, telling him that she agreed that life in prison without the possibility of parole was a more “suitable” punishment than lethal injection, the state’s default method of execution.

“Because I believe if you ever understand or feel the way I do, it will take the rest of your life to figure it out,” Strecker wrote in a statement that was read in court. “I know she has forgiven you. She was a wonderful, beautiful, forgiving Christian girl, and wants me [to be] too, so I can just remember her and not you anymore. May God forgive you for what you have done.”

The statements came as Martinez and prosecutors agreed to a plea deal that would spare him the death penalty. He will instead spend the rest of his life in prison for killing Greene and Kalb, as well as Victor Martinez, a 21-year-old friend of Martinez who was found shot twice in the head in a ditch in Gibsonton in 2009.

Prosecutors said Martinez lured Victor Martinez, of Brandon, to a remote area under the guise of picking up a package before shooting his friend — the pair were not related — and driving off with his car. Charles Andrew Martinez was initially considered a suspect in the killing, but investigators were unable to find enough evidence to arrest him, the newspaper reports.

Charges in connection with Victor Martinez’s death were then filed last year, after Charles Martinez was taken into custody for the murders of Greene, 25, and Kalb, 23, on Oct. 10, 2013.

As in the earlier killing, Charles Martinez was quickly considered a suspect in the deaths. He later surrendered to police on an unrelated warrant prior to being charged with the killings in 2014, the Tampa Bay Times reports.

The case against Martinez was delayed, in part, due to questions about the constitutionality of Florida’s death penalty and his mental health after being declared incompetent to stand trial in 2017. He then spent some time in a state hospital before being returned to custody, the Tampa Bay Times reports.

Jessica Kalb, Kalb’s sister, also addressed Martinez on Friday in court, telling him that she lost a piece of herself with the death of her sister.

“There are memories and moments that I wish I could share with her,” Jessica Kalb wrote in a statement. “She will never get married or have a family like I do now because you took that chance away.”
