He was admitted to St. Dominic Hospital Tuesday morning with chest pains. 
Hinds County Coroner Sharon Grisham Stewart says he was pronounced dead around 4:55 p.m. 

Lumumba won the Mayor's office in June 4, 2013, pulling 86% of the vote and defeating independent candidates Francis P. Smith, Jr. , Richard C. Williams and Cornelius Griggs.

Mayor Lumumba was born August 2, 1947 in Detroit, Michigan. He is the second of eight children born to Lucien and Priscilla Francis Taliaferro.

Mayor Lumumba earned his Bachelor's degree in Political Science from Kalamazoo College in Kalamazoo, Michigan. 

He later finished first in his law school freshman class before graduating cum laude from Wayne State University Law School.

Prior to his election as Mayor, Mr. Lumumba served as Jackson City Councilman for Ward 2. 

Mississippi Governor Phil Bryant released this statement: 

"Deborah and I are shocked and saddened by the news of Mayor Lumumba's passing and are praying for his loved ones. Just a short time ago, I had the opportunity to join the mayor in a church pew as we welcomed a new development to the city. His enthusiasm for Jackson will be deeply missed."
