In Oklahoma, a person convicted for killing a woman during the robbery of a house was killed.
And in Florida, another person was killed for rape and murder of a child and killing her grandmother.
Vandel Grisom, 56, was sentenced to death in Oklahoma for the 2005 murder of 23 -year -old Amber Mathews, who was shot in the head while trying to protect two young daughters of a friend.
The Oklahoma Department of Karcasions Department said in a statement, Grisom was declared dead 10 minutes after the execution process started in the state peninsula in Maclester.
This said that execution was done using a three-drug protocol: Midazolam, which causes the act of fainting, vekuronium bromide, which prevents respiration, and potassium chloride, which prevents the heart.
According to court documents, Grisom, a truck driver, and another man, Jesle Johns, broke into a Dreu Copes’ house, a friend of Mathews, with the intention of committing a robbery.
Grisom shot and injured Kopf and killed Mathews, while she was hidden in a bedroom in an attempt to mold two children of Kopf.
Johns was sentenced to life in prison without parole.
In Florida, 63 -year -old Edward James was also executed by deadly injections, an eight -year -old girl in 1993, for rape and murder of Tony Nyunar, and killing Betty Dick, 58 -year -old, her grandmother.
The Florida Department of Karcasions announced that James was killed outside Jacksonville in the north of the state, at Florida State Jail in Riford at 8:15 pm on Thursday night (0015 GMT Friday).
