The man who shot and killed two New York City police officers as they sat in their patrol car had posted angry messages on social media, ranting against the government and police, New York Police Department's Chief of Detectives Robert Boyce said Sunday.
Ismaaiyl Brinsley, 28, also posted messages of self-loathing and despair and made reference online to Michael Brown and Eric Garner, African-American men who were killed by police.
"I'm Putting Wings On Pigs Today. They Take 1 Of Ours, Let's Take 2 of Theirs," an Instagram post read, authorities said.
Brinsley had a lengthy criminal record. He was arrested 15 times in Georgia for assorted crimes and arrested four times in Ohio, Boyce told reporters Sunday.
He was in prison in Georgia between August 2011 and July 2013 for criminal possession of a weapon, Boyce said.
Brinsley had an address connected to him in Georgia but that appears to be his sister's home, and they are estranged, Boyce said. The gunman's connection to Brooklyn is that his mother lives there, but they are also estranged, the chief of detectives said.
On Saturday afternoon, Brinsley fired four rounds at officers Rafael Ramos and Wenjian Liu in the Bedford-Stuyvesant neighborhood. The officers, who were hit in head, were assigned from their normal downtown Brooklyn beat to an area of the borough with a high crime rate, authorities said.
New York City Police Commissioner William Bratton said the officers were shot "with no warning, no provocation."
First a soldier guarding a hallowed war memorial was gunned down in Canada's capital. Then shots erupted in the halls of the country's Parliament minutes later.
The two shootings in Ottawa Wednesday left lawmakers barricaded inside offices and parts of the city on lockdown for hours as police searched for suspects.
Ottawa Police lifted the lockdown Wednesday night and said there was no longer a danger to the public.
But many questions remain about the shootings: Who was the gunman? Why did he open fire? And was he acting alone?
"It appears there was just one shooter, and that shooter is dead," Ottawa Mayor Jim Watson told CNN's Anderson Cooper. "But it has been a traumatic experience, obviously, for not only our city but the country."
Investigators haven't provided any possible motives for the shooting. Canadian Prime Minister Stephen Harper didn't provide details about the investigation in a televised address to the nation Wednesday night.
"In the days to come, we will learn more about the terrorist and any accomplices he may have had, but this week's events are a grim reminder that Canada is not immune to the types of terrorist attacks we have seen elsewhere in the world," Harper said. "Let there be no misunderstanding: We will not be intimidated. Canada will never be intimidated."
It is unclear whether additional suspects were tied to the shootings or whether additional arrests have been made. The Royal Canadian Mounted Police said more information would be provided in a press conference Thursday.
As authorities continued to investigate, details began to emerge about the man they suspect was behind the shooting.
Michael Zehaf-Bibeau was identified by Canadian officials to their American counterparts as the suspected gunman, multiple U.S. officials told CNN.
Bibeau, who was born in 1982, was a convert to Islam and had a history of drug use before he converted, two sources said.
His passport had been confiscated by Canadian authorities when they learned he planned to go fight overseas, a U.S. law enforcement official told CNN's Susan Candiotti. The official said it was not clear when that happened.
Canadian broadcaster CBC reported that Bibeau had a record of drug arrests going back 10 years.

The U.S. Secret Service is planning to boost its presence and its surveillance measures around the White House on Monday after an Iraq war veteran, who is apparently suffering from PTSD, jumped over a White House fence.
Officers patrolling the area will be out in greater numbers and will be "looking for individuals who don't look like tourists," a federal law enforcement officer told CNN.
Two security incidents in two days have raised concerns about the safety at 1600 Pennsylvania Ave.
On Friday, Omar Gonzalez hopped the north fence and sprinted just past the north portico White House doors when he was stopped, Secret Service spokesman Brian Leary said.
Gonzalez carried a Spyderco VG-10 folding knife with a 3-and-a-half inch serrated blade in his pants pocket, according to an affidavit.
A Secret Service officer said he yelled at the intruder to stop. Gonzalez told a Secret Service agent "that he was concerned that the atmosphere was collapsing and needed to get the information to the President of the United States so that he could get the word out to the people," according to the affidavit.
President Barack Obama and his family were not at home at the time.

A Malaysia Airlines passenger jet crashed in a rebel-controlled part of eastern Ukraine on Thursday, spurring swift accusations from Ukrainian officials that "terrorists" shot down the aircraft.
The United States has concluded a missile shot down the plane, but hasn't pinpointed who was responsible, a senior U.S. official told CNN's Barbara Starr.
The Boeing 777 with 298 people aboard fell from the sky near the town of Torez in the Donetsk region of eastern Ukraine, officials said. A top Ukrainian official said the plane, which was on the way from Amsterdam to Kuala Lumpur, was flying at about 10,000 meters (nearly 33,000 feet) when the missile hit.
A radar system saw a surface-to-air missile system turn on and track an aircraft right before the plane went down, the senior U.S. official said. A second system saw a heat signature at the time the airliner was hit, the official said. The United States is analyzing the trajectory of the missile to try to learn where the attack came from, the official said.
The Obama administration believes Ukraine did not have the capability in the region - let alone the motivation - to shoot down the plane, a U.S. official told CNN's Jake Tapper.
Malaysian Prime Minister Najib Razak said the plane never made a distress call.
He called for an international team to have full access to the crash site.
"We must and we will find out precisely what happened to this flight. No stone will be left unturned," he said.
"If it transpires that the plane was indeed shot down, we insist that the perpetrators must swiftly be brought to justice," Najib said.
Ukrainian officials maintained that pro-Russian separatists were behind the crash.

Thirteen nuns and three workers kidnapped in late November from a Greek Orthodox monastery in Syria were freed Sunday, a pro-Syrian government news network and Lebanese state media reported.
A convoy of around 30 vehicles picked up the nuns and workers in one part of Syria and took them into Lebanon, the country's National News Agency reported late Sunday. The convoy traveled through Lebanon to another border crossing into Syria, the hillside village of Jdaidet Yabous. There, the group will be met by Greek Orthodox church officials, who will welcome them back into Syria, Syrian state news agency SANA reported.
The convoy was at one point delayed several hours for "logistical reasons" but later resumed en route to Jdaidet Yabous, Public Security Director Gen. Abbas Ibrahim told NNA.
When they did arrive overnight, the nuns - some smiling, some solemn and at least one of whom appeared to be being carried - were mobbed by an enthusiastic crowd that included church officials.
Ibrahim said that no money was paid to secure the release of the nuns, adding that it was part of a deal in exchange for 150 females that the Syrian government was holding.
Qatari intelligence chief Saadeh Kobeisi reportedly crossed deep into Syrian territory to obtain the release of the Syrian nuns. He crossed into Syria as part of a Lebanese Internal Security delegation, the state news agency said.
Senior Orthodox Bishop Lucas al-Khoury earlier Sunday spoke to pro-Syrian government Ikhbariya television. He stood on the Syrian side of the border hoping to greet the nuns and said the negotiations for their release took several months because the kidnappers "made false requests intended to stall the process."

A Kentucky pastor who starred in a reality show about snake-handling in church has died - of a snakebite.
Jamie Coots died Saturday evening after refusing to be treated, Middleborough police said.
On "Snake Salvation," the ardent Pentecostal believer said that he believed that a passage in the Bible suggests poisonous snakebites will not harm believers as long as they are anointed by God. The practice is illegal in most states, but still goes on, primarily in the rural South.
Coots was a third-generation "serpent handler" and aspired to one day pass the practice and his church, Full Gospel Tabernacle in Jesus Name, on to his adult son, Little Cody.
The National Geographic show featured Coots and cast handling all kinds of poisonous snakes - copperheads, rattlers, cottonmouths. The channel's website shows a picture of Coots, goateed, wearing a fedora. "Even after losing half of his finger to a snake bite and seeing others die from bites during services," Coots "still believes he must take up serpents and follow the Holiness faith," the website says.
On Sunday, National Geographic Channels spokeswoman Stephanie Montgomery sent CNN this statement: "In following Pastor Coots for our series Snake Salvation, we were constantly struck by his devout religious convictions despite the health and legal peril he often faced.
"Those risks were always worth it to him and his congregants as a means to demonstrate their unwavering faith. We were honored to be allowed such unique access to Pastor Jamie and his congregation during the course of our show, and give context to his method of worship. Our thoughts are with his family at this difficult time."
In February 2013, Coots was given one year of probation for crossing into Tennessee with venomous snakes. He was previously arrested in 2008 for keeping 74 snakes in his home, according to National Geographic. Tennessee banned snake handling in 1947 after five people were bitten in churches over two years' time, the channel says on the show site.
On one episode, Coots, who collected snakes, is shown trying to wrest a Western diamondback out of its nook under a rock deep in East Texas. He's wearing a cowboy hat and a T-shirt that says "The answer to Y2K – JESUS."
The pastor is helped by his son and a couple of church members.
"He'll give up, just sooner or later," one of the members says. "Just be careful. Ease him out."
The group bags two snakes, which a disappointed Coots says hardly justifies the trip to Texas.
"Catching two snakes the first day, 'course we'd hoped for more," Coots says in the video. "We knew that the next day we was gonna have to try to hunt harder and hope for more snakes."
