The Minnesota woman who shot video of her dying boyfriend after a police officer shot him last week says she realized the traffic stop was different when she heard fear in the officer’s voice.

Lavish “Diamond” Reynolds called into a Sunday morning service at The Potter’s House, aDallas megachurch, to talk about the death of her boyfriend, Philando Castile.

Reynolds says that when she heard the officer, “it instantly clicked to me that this was something bigger than myself and Phil.”

Reynolds cried as she recounted the shooting and said her daughter, who was shown on camera comforting her, is still telling her “it’s gonna be OK.”

The killing of Castile outside St. Paul and another black man in Baton Rouge, Louisiana, touched off protests. On Thursday, a gunman opened fire on police at one such protest inDallas, killing five officers.

Police say a vehicle struck a Dallas police car parked outside the home of one of five officers slain during a protest last week.

Fort Worth police say they are investigating whether the crash was an accident or deliberate.

Authorities are trying to locate the vehicle, which sped away after smashing into the driver’s side of the police car around 1 a.m. Sunday.

Nobody was hurt.

Two Dallas officers were assigned to the marked patrol car, but officials didn’t immediately say whether the officers were in the vehicle.

Authorities say the lone sniper in the Dallas attack was killed early Friday when an explosive on a remote-controlled police robot was detonated.

Police have arrested about 100 people in St. Paul during protests of the recent police killings of black men, including one outside Minnesota’s capital city.

Authorities say 21 St. Paul officers and six state troopers were hurt during the fracas late Saturday and early Sunday.

St. Paul Mayor Chris Coleman and Police Chief Todd Axtell are condemning the violence. Axtell calls the pelting of officers with rocks, bottles and other objects “a disgrace.”

The Star Tribune (http://strib.mn/29qNWkj) reports about half the arrests came during a blockade of Interstate 94 in St. Paul. About 50 arrests were made early Sunday in another part of St. Paul. The interstate reopened early Sunday morning.

The protest was among several demonstrations nationwide following the deaths of 32-year-old Philando Castile in suburban St. Paul and 37-year-old Alton Sterling in Baton Rouge, Louisiana.

San Antonio police say shots fired overnight near the department headquarters hit the building, but nobody was hurt.

Chief William McManus says investigators are trying to determine whether the building was targeted Saturday night or if someone was randomly firing.

Police detained one person for questioning after the man was seen running from the area.

Five police officers were killed after a sniper opened fire Thursday night in Dallas during a protest against the killings of black men last week by police officers in Louisiana and Minnesota.

Several San Antonio police officers who were in the headquarters Saturday night reported hearing gunshots. McManus says several shell casings were found in a nearby alley.

President Barack Obama says protesters who attack police officers are doing a disservice to their cause.

Obama said in Madrid after meeting with Spain’s acting prime minister that one of the great things about America is that individuals and groups can protest and speak truth to power. He says the process is sometimes messy and controversial, but the ability to engage in free speech has improved America.

Obama also cautions that if protesters paint police with a broad brush, they could lose allies for their cause. At the same time, he says that when police organizations acknowledge there is a problem stemming from bias, it will contribute to solutions.

Obama is cutting his first visit to Spain a day short because of a series of deadly shootings in the U.S.

Dallas police chief David Brown says the suspect in the deadly attack on Dallas police officers scrawled letters in his own blood on the walls of the parking garage where officers cornered and later killed him.

Brown told CNN’s “State of the Union” on Sunday that Micah Johnson wrote lettering in blood before heading upstairs and writing more in his own blood. He says the 25-year-old Army veteran wrote the letters “RB,” and that investigators are looking through things found in his suburban Dallas home to try to figure out what he may have meant by that.

The chief defended the decision to kill Johnson using a robot-delivered bomb, saying negotiations went nowhere and trying to “get him” in some other way would have put his officers in danger.

Brown says that during the roughly two-hour standoff in the garage, Johnson lied to and taunted the police negotiators.

Authorities say Johnson killed five police officers and wounded seven others and two civilians during an attack at a protest over last week’s killings by police of black men in Louisiana and Minnesota.

The gunman who killed five police officers at a protest march had practiced military-style drills in his yard and trained at a private self-defense school that teaches special tactics, including “shooting on the move,” a maneuver in which an attacker fires and changes position before firing again.

Micah Johnson, an Army veteran, received instruction at the Academy of Combative Warrior Arts in the Dallas suburb of Richardson about two years ago, said the school’s founder and chief instructor, Justin J. Everman.

Everman’s statement was corroborated by a police report from May 8, 2015, when someone at a business a short distance away called in a report of several suspicious people in a parked SUV.

The investigating officer closed the case just minutes after arriving at a strip mall. While there, the officer spoke to Johnson, who said he “had just gotten out of a class at a nearby self-defense school.”

The owner of a community social services organization says the gunman who killed five police officers at a Dallas protest march worked for his organization.

Dallas-based Touch of Kindness subcontracts with the state to provide care for people with disabilities.

Owner Jeppi Carnegie says that Micah Johnson was paid to care for his brother, who was in his early 20s.

Carnegie said Johnson, until his death this week, received an hourly wage to look after his brother at the home in Mesquite where both men lived with their mother. Carnegie said he spoke with Johnson only once by phone, for less than a minute, and only then to confirm that he would be taking care of his brother.

Johnson was killed Friday morning by police
