“Your conclusion?” Stone asked.
“I think the bomb could very well have been in the basketball and the ball was placed inside the root ball of the maple. That location would tally with the debris field and other indicators we found.”
“A bomb in a basketball?” said Chapman.
“It would work,” said Garchik. “And it’s been done before by a few people, all dead now. Cut it open, put the bomb inside, reseal it, pump it up so that if anyone held it, it would feel legit. I wouldn’t advise dribbling the sucker, though.”
“How was it detonated?” asked Stone.
“Remotely would be my best guess, right now. Not a timer.”
Stone said, “But we have information that the bomb dogs had patrolled the site the night of the bombing. Wouldn’t they have sensed it? You said they couldn’t be fooled by anything.”
“They can’t. But they do have limits.”
“What exactly are those limits?” asked Chapman.
“Typical scent radius for the dogs is about three feet in all directions aboveground. And they can sniff out explosives buried up to roughly the same distance belowground.” Garchik pointed at the crater. “This hole before the bomb went off was over four feet deep and well over eight feet across.”
“But uncovered,” Stone pointed out.
“Yeah, but the root ball was huge. Six feet wide by over three feet high.”
Stone realized something. “And there was yellow warning tape up cordoning off this area. So the dogs might not have gotten within ten feet of it.”
“That’s right,” said Garchik. “So whether the bomb was here when they made their pass or not, chances are good they wouldn’t have detected it unless their handlers took them past the tape and let them climb right on top of the root ball. Which I sort of doubt was the case.”
Stone’s gaze immediately swung toward the White House. “Then we need to talk to the people who installed it as soon as possible. But first we need to look at the video.”
“Video?” said Chapman.
“The video feed will show when that tree went in and who did it. It will also show if anyone went back in there afterward. And what they had with them. Like a bag big enough to place a basketball in.”
Garchik said, “It would be pretty hard to slip a basketball inside a root ball and not have someone see you. There’s a burlap sack around it to hold the dirt and roots together, but it would still be complicated. You’d have to get the ball there somehow, get down into the hole, slit the sack, put the ball in and somehow patch the sack back up.”
Chapman added, “And he couldn’t exactly waltz it past the White House guards. I’m assuming the workers have to go through checkpoints.”
“Yes, they do,” answered Stone. “And I would imagine an X-ray of the basketball would reveal the bomb inside?”
“Absolutely,” said Garchik.
“Then if one of the groundspeople was involved he didn’t take the ball through White House security.” He looked around. “But he could have come directly to the park to begin work on the tree. Someone could have given him the ball then. The White House wouldn’t be involved at all.”
“Which would be captured on the video,” said Garchik. “We’ll have to check that angle, but it seems way too easy to detect on our part.”
Stone said, “Which means we’re missing something.” He looked down at the crater. “Let’s check that video feed. Right now.”
CHAPTER 27
A few minutes later they were standing in the FBI’s command post on Jackson Place. They had called in two Secret Service agents, who huddled with them around the large TV screen. The feed they would be looking at had come from the Secret Service’s archives.
“We keep the images for a minimum of fifteen years,” explained one of the Secret Service agents.
“You’re not the only agency with electronic eyes on the park, though,” said Stone.
The same agent smiled. “We all have peepers on our little slice of Hell’s Corner. In an ideal world we all share what we see, but this is far from an ideal world.”
“What exactly are you looking for?” asked the other agent.
Stone explained about the tree being planted, and also about the bomb dog going near the tree.
Agent Garchik had stayed behind in the park to keep going over the crime scene, but Tom Gross had joined them after being called by Stone. The FBI agent said, “We need to see the entire feed from the time the tree was delivered to the moment the bomb went off.”
They were shown this feed from three different angles. It took a long time, even though the security guard was able to speed up the frames without any significant detail being missed. At the end they stared at the screen with the same unanswered questions.
Gross said, “The dogs did make a pass, but they stayed outside the tape line. That was a big hole in the security wall. Secret Service is going to get dinged for that.”
The two agents exchanged glances and grimaced but said nothing.
“And there wasn’t even a hint of anyone planting anything in that hole,” added Chapman.
Stone said, “You’re sure this is all the footage?”
One of the agents said, “That’s it.”
Gross, Stone and Chapman left the command center. On the way back to the park Gross said, “I can’t remember the last case I had where not only haven’t I taken a step forward, I keep taking steps back.”
Stone closed his eyes and recalled what he had seen on the video. A crane had lifted the large tree up into the air. Then a crew of National Park Service personnel in their green-and-khaki uniforms had moved in and helped direct the placement of the maple into the hole.
He opened his eyes. “There had to be a staging area for the tree. Where it was kept before being installed? That wasn’t on the video.”
“That’s right,” said a hopeful-looking Gross.
Chapman added, “And the time stamp on the video shows that the tree was put in a day before the bombing happened. So why was the hole still uncovered?”
Gross said, “I think we need to find answers to those questions.”
A moment later his phone rang. He talked for a few moments and then clicked off. “We got a hit on the jogger. Missing persons report was phoned in a few hours ago. Family member. Matches the description, and he was in the vicinity of the park.”
“Why so long to call it in?” asked Stone.
“Something we’ll have to find out when we talk to them.”
“I think we should split up,” said Stone. “You and your men can handle the groundspeople and Chapman and I can talk to the family members. You have the address?”
Gross gave it to him. As they were parting company the FBI agent said, “Now we’ve only got the suit to track down.”
Stone never turned around. “Yeah,” he said over his shoulder as Chapman marched along beside him.
When they got to her car she said, “You know you could be charged with withholding vital evidence in an investigation. With obstruction even.”
“If you think that’s the case, feel free to report me.”
The two looked across the width of the rental at each other.
Chapman finally sighed. “I don’t think it would further my career to pull the rug out from under my boss. So just get the hell in the car. ”
When the doors plunked closed she threw it into gear. “Where to?”
Stone gazed down at the slip of paper that Gross had given him with the address. “Anacostia. Make sure you keep your gun handy.”
“Is it dangerous, then, this Anacostia?”
Stone thought for a few moments before replying, “I guess less dangerous than Lafayette Park, actually.”
