BATON ROUGE, La. — The Latest on the fatal shooting of three law enforcement officers in Baton Rouge, Louisiana. (all times local):

Updated 11:07 a.m.: A former Marine dressed in black and carrying extra ammunition set out to ambush police in Baton Rouge, authorities said Monday, a day after three law enforcement officers were killed in the attack.

The gunman’s “movements, his direction, his attention was on police officers,” state police Col. Mike Edmonson said. He would not elaborate but said the shooter was definitely “seeking out” police.

Three other officers were wounded Sunday, one critically. The gunman, identified as 29-year-old Gavin Long of Kansas City, Missouri, was killed at the scene.

In online posts, a man using an alias of Long’s said protests alone do not work, and that people must fight back after the deaths of black men at the hands of police.

Documents show that Long sought to change his name last year to Cosmo Setepenra. A website using that name links to online books about nutrition, self-awareness and empowerment. The man describes himself as a “freedom strategist, mental game coach, nutritionist, author and spiritual advisor.”

In a video posted July 10, the man says he’s speaking from Dallas after the fatal attack on police officers there during a march over the deaths of black men at the hands of law enforcement. The man also discusses the protests in Baton Rouge and what he perceived as oppression.

He says: “You’ve got to fight back. That’s the only way a bully knows to quit.” In an earlier video, the man says that if anything ever happens to him, he doesn’t want to be linked to any groups, and mentioned once belonging to Nation of Islam.

Updated 8:45 a.m.: Clark Atlanta University officials say Baton Rouge gunman Gavin Eugene Long was briefly enrolled at the Atlanta university during the 2012-13 academic year.

Clark Atlanta said in a statement Monday morning that the university “categorically denounces this heinous act.”

Updated 8:35 a.m.: The man who killed three law enforcement officers in Baton Rouge sought to change his name last year and said he was part of a largely black group that claims to separate from state and federal governments.

Gavin Eugene Long, a black man whose last known address was in Kansas City, Missouri, carried out the attack Sunday on his 29th birthday. Police say he also wounded three officers before he was killed.

He sought to change his name to Cosmo Setepenra in a document filed in May 2015 with the Jackson County Recorder of Deeds. He also refers to himself as a member of the Washitaw de Dugdahmoundyah, also known as the Washitaw Nation.

The groups says it’s a sovereign Native American nation within the boundaries of the U.S.

The name-change document ends: “Standing firm on the Ancient Principles of, LOVE, TRUTH, PEACE, FREEDOM AND JUSTICE.”

Updated 7:20 a.m.: Businesses around a shooting that killed three law enforcement officers in Baton Rouge, Louisiana, are reopening as police continue investigating the scene.

Customers were buying coffee and breakfast sandwiches Monday at a B-Quik convenience store near where officers first engaged the gunman less than 24 hours earlier. Next door, workers prepared for the day at a car wash where the gunman was cornered.

Businesses on two sides of the scene of a gunbattle were riddled with at least eight apparent gunshots. Investigators examined a hole in a window at a fitness supply business as news crews worked nearby, and wood covered another window that was shot out.

Authorities say two city police officers and a sheriff’s deputy died in the shooting Sunday morning, and the gunman was killed by law enforcement. Three other officers were wounded. The identities of the slain officers and two of those wounded are known. But the name of the third wounded officer hasn’t been released. Baton Rouge police Sgt. Don Coppola said in a text message Monday that officials plan to release that name, “just not sure exactly when.”

Updated 7 a.m.: U.S. Attorney General Loretta Lynch says she condemns the attack in Baton Rouge “in the strongest terms possible” and says federal law enforcement agencies are helping on the ground.

Lynch said Monday in Washington that “families are again mourning loved ones robbed from them by senseless violence. … And all of us are again heartbroken at the news of yet another tragedy.”

She invoked a Facebook post by slain officer Montrell Jackson. Days ago, he wrote that he received “nasty, hateful looks” while in uniform but also said, “Please don’t let hate infect your heart.”
