Update: Police issued an apparently contradictory statment later on Friday that the officer who killed Michael Brown might not have been aware of the robbery when he shot the teenager. Police say the officer stopped Brown and his friend for jaywalking, and that the encounter was completely unrelated to the earlier robbery.

A police officer who shot and killed 18-year-old Michael Brown in Ferguson, Missouri, over the weekend was on his way to a robbery call when he ran into the unarmed teenager, police said during a news conference on Friday.

Ferguson police released the name of the officer who shot Brown and provided more details about the events that led to his death. Darren Wilson, a 28-year-old white man and six-year veteran of the police force, was identified as the officer.

The police report from a convenience-store robbery that happened on Saturday names Brown as a suspect. He and friend Dorian Johnson, who witnessed Brown's shooting, were allegedly trying to steal cigars. Johnson's lawyer has since confirmed to MSNBC that Brown took cigars from the store.

There was allegedly an altercation between Brown and a person who appears to be a store clerk as Brown was attempting to steal from the store, according to the report.

Wilson encountered Brown at about 12:01 p.m., Ferguson police chief Thomas Jackson said on Friday. Brown had been shot by the time a second officer arrived on scene at 12:04 p.m.

A description of the alleged convenience-store robber was dispatched on police radio as Wilson was in the area, Jackson said. Shortly after, Wilson stopped Brown nearby.

Here's the police report:

Police also provided stills from the convenience-store surveillance camera:

There are conflicting reports about what happened the day Brown was shot. The slain 18-year-old's friend Johnson — an eye witness — says Brown had his hands up when he was shot, but police say Brown lunged for Wilson's gun.

Brown's family and their attorneys released this statement Friday:

Michael Brown’s family is beyond outraged at the devious way the police chief has chosen to disseminate piece mil [sic] information in a manner intended to assassinate the character of their son, following such a brutal assassination of his person in broad daylight.

There is nothing based on the facts that have been placed before us that can justify the execution style murder of their child by this police officer as he held his hands up, which is the universal sign of surrender.

The prolonged release of the officer’s name and then the subsequent alleged information regarding a robbery is the reason why the family and the local community have such distrust for the local law enforcement agencies.

It is no way transparent to release the still photographs alleged to be Michael Brown and refuse to release the photographs of the officer that executed him.

The police strategy of attempting to blame the victim will not divert our attention, from being focused on the autopsy, ballistics report and the trajectory of the bullets that caused Michael’s death and will demonstrate to the world this brutal execution of an unarmed teenager.

Massive protests erupted in Ferguson after Brown's shooting, capturing a national spotlight and bringing attention to the militarization of police in America. Local police in Ferguson have been criticized for using riot gear, tear gas, dogs, and rubber bullets to control the protests that followed Brown's shooting.

The mood in Ferguson improved significantly after the governor brought in Highway Patrol Captain Ron Johnson, who's African-American and a Ferguson native. Johnson and other members of the patrol have used a different approach to crowd control, mingling with the protesters and ditching the riot gear.
