ISIL seeks to recruit African Americans after Baton Rouge, Dallas attacks

In a video posted July 10, Long, as Setepenra, said he was speaking from Dallas after another black man had killed five police officers there.

In the wake of the shooting, a source briefed on law enforcement's investigation told ABC News it appeared that Long showed support online for the Moorish Science Temple of America, which was described in an unrelated lawsuit as a group that believes the descendants of slaves are not subject to US laws. The motive was not immediately clear. Another wounded deputy and police officer have wounds not considered life-threatening, law officers said. The gunman was killed at the scene.

There is not an "active shooter scenario" in Baton Rouge, said Col. Michael D. Edmonson, superintendent of the Louisiana State Police. The officer then left the scene and "that's when the call comes in to say there was an individual ... with a rifle".

The shooting happened early Sunday, less than 1 mile from police headquarters. As more and more details about the case slowly emerge, so do details of who the shooter was. He urged anyone else with information about Long to come forward.

President Barack Obama is asking the American people to make certain the killer's work to divide the public would be in vain. Long, who was black, served in the Marines from 2005 to 2010, reaching the rank of sergeant.

Although he was believed to be the only person who fired at officers, authorities were investigating whether he had some kind of help. M. Doug Cain, spokesman for the Louisiana State Police, said, according to the Los Angeles Times. They were later released without any charges being filed.

While in the military, Long was awarded several medals, including one for good conduct, and received an honorable discharge. He served in the military for five years as a data network specialist. The University of Alabama issued a statement saying Long attended classes for one semester in the spring of 2012.

Thomas Glover, a Dallas police lieutenant and president of the Black Police Association of Greater Dallas, said dialogue needs to be followed by action. Police raided a house associated with him in Kansas City hours after the shootings.

Sunday's incident was the latest in a series of deadly encounters in the United States involving police and black men that have sparked a national debate over race and policing.

Dabadie made a similar point last week, after three people were arrested for allegedly stealing weapons to use to shoot police officers.

Also still hospitalized is deputy Bruce Simmons, 51, Sheriff Sid Gautreaux Monday said Monday. The next day, a black gunman in Dallas opened fire on police.

Airline Highway at Old Hammond Highway was reopened to traffic around 8 p.m. Sunday. Baton Rouge police are believed to have responded to a report of a man with an assault rifle and were met by gunfire.

Below is everything we now know about Long.

Police said they had not ruled out but had found no evidence to confirm a link with the Sterling shooting.

"At the Department of Justice, we are determined to do everything we can to bridge divides, to heal rifts, to restore trust, and to ensure that every American feels respected, supported, and safe", Lynch said in remarks prepared for a conference of black law enforcement officers in Washington. The recording lasts about 17 minutes and includes urgent calls for an armored personnel carrier called a BearCat.

Omoruyi also says Long was "outraged" by the deaths of Alton Sterling in Louisiana and Philando Castile in Minnesota - but that Omoruyi couldn't have imagined that anger would turn into violence. "It doesn't further the conversation".
