There are 3 women on Florida's death row. Here's the killers' backstories.

Only three women are currently on death row in Florida, including Tina Brown of Pensacola, who is attempting to appeal her sentence for the horrific murder of Audreanna Zimmerman, who was shocked with a stun gun, beaten, and set on fire. Here’s a look at the women of death row.

Tina Brown of Pensacola is on death row for murdering neighbor

Tina Brown, 52, arrived on death row in October 2013 for the brutal murder of her neighbor, 19-year-old Audreanna Zimmerman. Brown, with help from a friend and her then 16-year-old daughter, Britnee Miller, ambushed Zimmerman in a trailer, attacked her repeatedly with a stun gun, gagged her, stuffed her in the trunk of a car, drove her into the woods, beat her with a crowbar, doused her with gasoline, set her on fire and left her to die.

Despite being severely burned, Zimmerman managed to walk to about a third of a mile to residence and seek help. She reportedly named her attackers and asked EMTs to protect her children. She died in an Alabama burn ward 16 days later.

Although Brown has not denied her involvement in the murder, she has sought to have her conviction and sentence overturned in a series of appeals. In a 2022 motion to vacate her conviction and sentence, Brown's attorneys claimed a key witness against Brown, Corie Doyle, had lied on the witness stand at the behest of Heather Lee, another co-defendant in Zimmerman's murder. Lee, a friend and neighbor of Brown, was an accomplice in the killing, and she was sentenced to 25 years in prison after making a plea agreement with the state and testifying against Brown.

Margaret Allen of Brevard County is on death row for murdering her housekeeper

Margaret A. Allen was sentenced to death on May 19, 2011, after being convicted in the kidnappings and death of her housekeeper, friend, and neighbor, Wenda Wright, in Brevard County in 2005.

Margaret Allen, 57, was found guilty of torturing and murdering her former housekeeper, Wanda Wright, in 2005 after a dispute over possible stolen money. A jury in 2011 unanimously recommended the death penalty for Allen after she and two associates disposed of Wright's body in a wooded area near Mims.

Court records show Allen accosted Wright after a missing purse with $2,000 inside. When Wright denied stealing the money, Allen began beating her before pouring bleach and other household chemicals down her mouth.

Allen then put tape over the victim's mouth and strangled her to death with a belt at her Robbins Avenue home.  Two accomplices, James Martin and Quinton Allen, were convicted of helping Allen bury Wright's body in a remote area of Brevard County near State Road 46 in February of 2005.
