(CNN) -- An Alabama robbery suspect fatally stabbed a police officer in jail, escaped in a stolen patrol car and wounded another officer before he was killed, authorities said Friday.
The chain of events, which left Mobile, Alabama, mourning the loss of an officer, started early Friday when Lawrence Wallace Jr. was in a store.
Wallace, who was carrying a lighter and lighter fluid, stormed the front counter of the store and demanded money, said Ashley Rains, a spokeswoman for the Mobile police.
As the cashier frantically tried to open the register, Wallace jumped on the counter and began spraying lighter fluid on the floor, triggering a blaze.
An off-duty police officer happened to be shopping at the store and tackled Wallace, Rains said.
He was taken to Mobile's metro jail, where he was somehow able to stab and kill Officer Steven Green and escape in a patrol car, police said.
At some point during the manhunt for Wallace, he abandoned the police car and hid under a home. The suspect shot another officer in the arm as police tried to apprehend him. That officer was treated and released from a hospital, police said.
After a standoff, Wallace, 24, was shot and killed, police said.
Mobile Mayor Samuel Jones said his community lost a good officer.
"This officer was very, very well respected," Jones said. "We are all very saddened, certainly wish the family our deepest sympathy."
