Ifeoma Kalu, who died in the United States at age 61, is survived by her husband and four children.

He sympathised with Senator Kalu, his family and the entire people of Abia State.
The Governor described the death as shocking and a great loss to Kalu and urged the former Governor of Abia State, members of the immediate and extended families, the deceased’s friends and associates to take the demise of the late Ifeoma in good faith, praying that God would comfort them.
He said, “On behalf of my family and the people of Lagos State, I commiserate with former Governor of Abia State and Senate Chief Whip, Senator Orji Kalu on the demise of his beloved wife of 33 years, Mrs. Ifeoma Kalu.
“I also sympathise with all the children of the deceased – Neya Kalu, Michael Kalu, Olivia Kalu, and Nicole Kalu over the death of their mother.
“No doubt the death of a loved one is usually a painful episode in our lives because it is irreparable but we must always take solace in God for a good life spent by the late Ifeoma Kalu during her lifetime.
“Mrs Ifeoma was a woman of virtue who committed herself to the service of God and humanity as well as a partner, friend, wife, and great supporter to her husband, Senator Orji Kalu.
“I pray for the repose of the late Mrs. Ifeoma’s soul. God will grant her eternal rest and grant Senator Kalu, his children, and the deceased family the fortitude to bear the irreparable loss.”
