Former colleagues 'flabbergasted' co-worker is accused in attack
Garry Reynolds Jr. said he worked with Thomas Sanford at the Coca-Cola distribution center in Flint about 10 years ago and had known him both when he was single and then when he got married and became a father.
Friends at work supported Sanford as his son, Brantlee, was going through operations for his medical condition, Reynolds said.
“He loved his son,” Reynolds said. “He loved that boy.”
Reynolds couldn’t recall any red flags at work involving Sanford or complaints about his behavior.
“He was hilarious,” Reynolds said. “That’s why we’re all so stunned, because he was this really good guy. This was a guy that planted sunflowers. He had a large field of sunflowers. They’d all come up at once, and he would let people come and take pictures in his field, just because it made people happy. It wasn’t for a cash crop.”
Reynolds said he wasn’t sure what Sanford was doing for work in more recent years, and he mostly stayed in touch through his wife on social media.
Former colleagues, he said, were “flabbergasted” to learn Sanford was named as the suspect.
“Everyone’s just going, ‘What happened?’” Reynolds said. “Where in his life did it crack?”
EXCLUSIVE: Shooter's family has 'no answer' for church attack
Thomas Sanford, the shooter's father, said today that his family is "devastated" and doesn't know what to think about their son's actions.
In an exclusive statement to NBC News, Thomas Sanford described his son as a loving father and husband. The family also extended their prayers to the Grand Blanc community and everyone affected by the church attack.
"We are completely in shock over this; we have no answers," the statement said. "We are asking for privacy as we grieve our loss and those of the others."
Officials looking into IEDs left behind in suspect's car
Officials continue to investigate a number of improvised explosive devices found in the suspect's car.
Bureau of Alcohol, Tobacco, Firearms and Explosives special agent James Dier told NBC News the IEDs were "pretty basic in nature" and described them as "consumer fireworks taped together." He said that other consumer-grade smoke machines were found but that they would only create smoke.
None of the IEDs were set off, Dier said.
Dier maintained that he did not know why the IEDs were taken to the scene and said officials are still trying to determine the motive for the attack.
"We're going to look under every stone. Look, turn every piece of paper over and look and try to get to the very heart of the matter," he said.
Dier said he doesn't believe the attack was very planned out considering what officials have learned so far, but he said it must have been planned at least to some extent in the suspect's mind.
"There's no real science to this. It's just, some people hit a breaking point, and whatever that breaking point was for him, he decided to act," Dier said.
All of the deceased victims died from gunshot wounds, Dier said, clarifying that no one died in the fire.
2 patients remain in critical condition, doctor says

Danic said a number of the hospital's resident physicians were at the church at the time of the incident, describing them as "heroes."
"Not only were they victims, they are also first responders," Danic said. "And having your friends and family come in injured and take care of them is a really incredible experience."

The investigation continues, but officials are no longer searching for people in the remains of the church, Grand Blanc Township Police Chief Bill Renye said.

Victim recounts church shooting, calls for the country to 'come together'
Paul Kirby, 38, was at church yesterday with his wife and two sons when he saw a chapel wall buckle and heard a loud boom.
The church fell silent as Kirby and some others went outside to see what had happened, he said. They thought a driver had run off the road and hit the building, most likely needing help.
Instead, Kirby said, he saw a gunman get out of the car that slammed into the church and begin to open fire about 20 yards from where he stood. Kirby told NBC News that he ran toward the church doors, but not before shrapnel struck his left leg and right foot.
Kirby said it still hasn’t hit him that he was wounded in a mass shooting.
"I am extremely lucky to be alive because of how close he got to me, and the two people who went out in front of me were shot," he said.

Kirby said he found his family inside and piled nine people into their car to drive to safety. He said he saw people stay back to help those who had been shot and kids to get out of the building.
"Once we got out, I gave my boys a hug," Kirby said.
Kirby said he did not see the shooter pouring gasoline on the church or setting it on fire. He also said that he didn't recognize the man and that he had never seen him at church before.
The entire event was a blur, Kirby said, but he said he didn't hear the gunman say anything before he began shooting.
Asked what he thought the motive was, Kirby instead said, "Let's not make this political."
"Let’s not make this about anything. It’s something that just happened," he continued. "Let’s mourn and move on. Let’s not divide the country about it; we need to come together."
