Johnson
told police negotiators that he was upset about recent police
shootings, that he wanted to kill white people -- especially white
officers -- and that he acted alone, the police chief said.
"We saw no other option but to use our
bomb robot and place a device on its extension for it to detonate where
the suspect was," Brown said. "Other options would have exposed our
officers to grave danger. The suspect is deceased as a result of
detonating the bomb."
Johnson had no criminal record or known terror ties, a law enforcement official said.
He
served in the U.S. Army Reserve from March 2009 to April 2015, training
as a carpentry and masonry specialist, according to Pentagon records.
Johnson was deployed for about seven months in Afghanistan, from late
2013, and received an honorable discharge.
Johnson's
neighbor, Wayne Bynoe, said police cars were outside his home Friday.
Johnson lived with his mother and kept to himself, Bynoe said.
Johnson had at least two weapons with him -- a rifle and a handgun, two law enforcement officials said.
One
of the officials, familiar with the latest information from the Dallas
police investigation, said the rifle was an SKS semi-automatic. The
other official said Johnson legally bought multiple firearms in the
past.
Witnesses said protesters were marching peacefully in downtown Dallas when the gunfire started Thursday night.
Crowds ran into a parking garage,
witnesses said, and spilled out after word spread a sniper was nearby.
"Everyone was screaming, people were running," said witness Clarissa Myles. "I saw at least probably 30 shots go off."
Police
initially said at least two snipers fired "ambush-style" from an
"elevated position" before they exchanged gunfire and negotiated with a
suspect, later identified as Johnson, for hours at a parking garage in
downtown Dallas.
Before authorities
killed him with an explosive, Johnson told negotiators more officers
were going to get hurt, and that bombs were planted all over downtown.
Police found no explosives during sweeps of the area, Dallas Police Maj. Max Geron said.
The victims
The five slain officers were identified on Friday.
Dallas
Police Officers Lorne Ahrens, a 14-year veteran of the department, and
Michael Smith, a 27-year veteran, were both killed, according to local
media reports and Smith's sister, who spoke to CNN affiliate KFDM.
CNN
affiliate WDIV said Dallas officer Michael Krol was killed. The last
two officers were Dallas officer Patrick Zamarripa and DART Police
officer Brent Thompson.
Police have
said at least 10 officers were shot by a sniper and one officer was
shot in a shootout at the parking garage. It's not clear where the 12th
officer was shot.
A few of the wounded officers remain hospitalized, police said. Brown called for the community to support them.
"We
don't feel much support most days. Let's not make today most days,"
Brown said. "Please, we need your support to be able to protect you from
men like these, who carried out this tragic, tragic event."
The suspects
Though authorities said they're sure Johnson was the only shooter, they don't know if he had accomplices.
"I'm
not going to be satisfied until we've turned over every stone," Brown
said. "We've got some level that this one suspect did do some of the
shooting. But we're not satisfied that
we've exhausted every lead," he
said. "So if there's someone out there who's associated with this, we
will find you, we will prosecute you, and we will bring you to justice."
The
Dallas police chief told reporters it's too soon to speculate on the
suspect's motives, and it's unclear whether more suspects are on the
loose.
Other shootings of police
Three other shootings endangered police around the same time.
In
Bristol, Tennessee, a man opened fire on motorists early Thursday at a
motel and along the Volunteer Parkway, killing a woman and wounding
three people, including a police officer, the Tennessee Bureau of
Investigation said.
The TBI said a
preliminary investigation reveals the suspect, Lakeem Keon Scott, 37,
may have targeted individuals and officers after being troubled by
recent incidents involving African-Americans and law enforcement
officers in other parts of the country. Witnesses said they heard
someone yell, "Police suck! Black Lives Matter!" before bullets were
fired, the TBI said.
Scott was wounded by police, arrested and questioned at a hospital, the TBI said.
In
the St. Louis area, a police officer was shot in the back of his neck
Friday morning by a suspect stopped for a speeding violation, Ballwin
Police Chief Kevin Scott said. The officer was walking back to his
patrol car when the suspect ran toward him, firing three shots from a
semi-automatic handgun, Scott said. The suspect was arrested and the
office was in critical condition, Scott said.
In
Valdosta, Georgia, a police officer was shot Friday morning by a man
who placed a 911 call, the Georgia Bureau of Investigation said. The
officer, who is now in stable condition, went to an apartment complex to
check on a reported car break-in and was shot twice when he exited his
patrol vehicle, the GBI said.
The
officer returned fire and wounded the shooter, who was identified as the
caller and arrested. The GBI said there was no connection to the Dallas
shooting.
A number of police
departments across the country, including Chicago, Philadelphia and
Cincinnati, decided that officers should be paired-up for an indefinite
period. Chicago police said the move was made "to increase visibility
and strengthen officer safety."
The protests
The
shootings occurred as many Americans nationwide took to the streets to
demand answers over the killings of two black men by police in two days.
In Minnesota, crowds gathered near the spot where an officer killed
Philando Castile in a car Wednesday.
Hundreds
of miles away, protesters marched outside a convenience store in Baton
Rouge, Louisiana, where Alton Sterling was fatally shot Tuesday while
police tackled him in a parking lot.
Minnesota shooting
Both killings were captured on video and posted online.
In Minnesota, the shooting of
Castile was remarkable -- and heartbreaking --
because his fiancée streamed the immediate aftermath live on Facebook.
As her 4-year-old sat in the back seat,
Diamond Reynolds calmly narrated what was going on and showed viewers
the dying man groaning and bleeding in the front seat.
Castile,
a school food services worker, was shot in Falcon Heights, outside
Minneapolis, when a police officer pulled him over because of a broken
taillight, said Reynolds, who was in the car with him.
"He
let the officer know that he had a firearm and he was reaching for his
wallet and the officer just shot him in his arm," she said as she
broadcast the Wednesday shooting on Facebook.
"Oh God, please don't tell me my boyfriend is dead," she said.
Falcon Heights
contracts with the City of St. Anthony Park for police services. Friday, Black Lives Matter held a new conference and called for Falcon Heights to terminate that contract.
Baton Rouge shooting
Sterling, 37, was killed Tuesday near a convenience store in Baton Rouge, where he regularly sold CDs and DVDs.
A
homeless man approached Sterling on Tuesday and asked for money,
becoming so persistent that Sterling showed him his gun, a source told
CNN.
The
homeless man called 911 and police arrived at the store. Police tackled
Sterling to the ground, and shot him several times, video shows.
A
law enforcement source told CNN that the officers pulled a gun from
Sterling's body at the scene. No further details were provided on the
type of firearm.
The convenience
store quickly became the site of protests. Flowers and signs piled up in
a makeshift memorial. Protesters chanted "Hands up, don't shoot," the
line made famous in the Michael Brown shooting in Ferguson, Missouri,
about two years ago. Brown was also shot by a police officer.
Protests against police shootings were held in most major cities, including Chicago and New York, Thursday night.
