HE APARTMENT HAD changed since Robie had last been there. The cops were doing a thorough forensics search and fingerprint powder residue, evidence markers, and thirty-five-mil cameras flashing off were evident throughout the small space.

Robie eyed a sealed evidence box on the particleboard table.

“Is that Agent Wind’s work papers? Laptop?”

Vance nodded. “It is. We’ve sealed it pending your agency’s review. I’m cleared all the way on things like that, but I didn’t want to step on your toes.”

“Appreciate that.”

“But we will need to be read in. If there’s something in those docs and files that got her killed, the Bureau needs to know it.”

“Understood. I can have the review done today and you can be read in directly after.”

Vance’s smile was guarded. “I never met a more cooperative agency liaison. You’re going to spoil me.”

“I’ll do my best,” Robie said.

Until I stop being cooperative, he thought.

“There were pick marks on the front door lock,” Vance said. “They were subtle, so the person knew what he was doing. Follow me.”

They walked into the bedroom.

Robie looked around. The bodies had been removed, but in his mind he still saw them on the bed, their heads pulverized.

“Wind and her son Jacob were found on the bed. She was holding him. One shot killed them both.” She pointed to the shattered window. “We’ve run a trajectory. Shot came from that high-rise building, well over three hundred meters away. We’re pinpointing the exact room. The building is abandoned, so it’s doubtful anyone saw anything. But we’re still following up. If we’re lucky, the shooter left something behind.”

You won’t be that lucky, thought Robie.

“But you said you found a Glock round in the floor. How does that tie into a shot at that distance? It wasn’t a pistol round that killed them. Had to be a rifle round.”

“I know. That’s what’s so puzzling. If I have to speculate, there were two people involved. The person in this room last night fired a shot into the bed. It went through and lodged in the floor. That slug matched the gun we found underneath a car next to the bus explosion. But the kill shot came through the window, hit Jacob, passed through his head, and impacted his mother. Death was instantaneous for both. Or so the ME said.”

Robie remembered the look on Jane Wind’s face and wondered how truly “instantaneous” her death had been.

“So two shooters? Doesn’t make a lot of sense,” he said.

“It makes no sense,” replied Vance. “But that’s because we don’t have enough facts. We collect enough of those it will make sense.”

“I appreciate your optimism.” Robie stood in front of the bed, in nearly the exact spot from which he’d fired his weapon the night before. “So the shooter who presumably broke into the apartment fired into the bed. Where was the slug found?”

Vance motioned for one of her techs to move aside the bed. Robie saw the evidence marker next to a hole in the wooden floor.

Robie held up an imaginary pistol. He aimed and clicked his finger while Vance watched.

“He would have been standing about here,” said Robie, who of course knew this for a fact. “The mattress and box springs seem really thin. I doubt they would have diverted the flight path of the round much, not at this close range.”

“That’s what I figured too,” said Vance.

“No other wounds on the bodies? The round fired into the mattress didn’t hit them?”

“Negative. No human residue on it and no other wounds on the victims.”

“So he fired a shot into the mattress why? To get their attention?”

“Maybe,” said Vance.

“Were they awake when they were shot?”

“Looked to be. The position where they fell on the bed leads me to believe they were awake when they were killed.”

“So he fires, but doesn’t hit them. He did it to get their attention, or maybe to get them to be quiet. Anyone report hearing any screams?”

Vance sighed. “If you can believe it, the only person who lives on this floor and was here last night is an old woman who’s both deaf and blind. She, of course, heard nothing. The only other floor resident was working in Maryland at the time. The apartments above and below this one are vacant.”

Oh, I believe it, thought Robie.

“But the round from outside killed them,” he said. He went over to the broken window and examined it. He looked outside beyond to the building he could not see last night. The alleyway was down below. The one he had been supposed to use to make his escape. There were other buildings separating the two high-rise structures, but they were all one-story. The shooter would have had a clean shot.

“Okay, gunman inside. Shooter outside. Gunman fires into the bed. Shooter outside kills Agent Wind and her son.” He turned back to Vance. “Wind had two sons.”

“That’s the other really puzzling piece. Her other son is less than a year old. His name is Tyler by the way. He was found by a woman on the third floor.”

“Found how?”

“It’s crazy, Robie. Someone knocked on her door shortly after the Winds were killed. At least according to the preliminary time of death the ME gave us. The woman opened the door and there was Tyler in his car carrier sound asleep. She recognized him as Wind’s son and tried phoning her, then went to her apartment. No one answered so she called the cops. That’s when the bodies were discovered.”

“You have a theory for that?”

She shook her head. “I know this sounds unbelievable, but it might be that whoever broke into Wind’s apartment took the kid down there.”

“Why?”

“Why kill an infant? He can’t testify against you.”

“They had no problem killing the other son,” countered Robie.

“Been thinking about that. Look at the hole in the window and then look at the bed. If Wind had grabbed up her other son, maybe to protect him against the intruder, he might have been on the left side—in other words, facing the window.”

Robie finished this thought for her. “Shooter fires, really only aiming to hit Wind, but the shot hits the kid first and then her. Maybe he intended to kill them both, or at least wanted to kill Wind and if the kid was in the way, too bad.”

“That’s how I see it,” agreed Vance. “So that sets up an interesting possibility.”

“Such as?”

“How’s this for a theory? Intruder comes in, just a standard burglary. He doesn’t mean to but somehow awakens Wind and her son. He fires a shot into the bed to keep them quiet. At the same time, unbeknownst to him or Wind, of course, a shooter is targeting her from that other building at the exact same time. He fires, killing her and her son. The intruder is stunned. He could have ducked down, thinking he might be shot next. He sees the other kid in the carrier, grabs it up, and during his escape drops him off at another apartment. Then he gets away.”

“I thought you didn’t believe in coincidences,” said Robie.

She smiled weakly. “I know. It’s like the mother of all coincidences, isn’t it?”

It’s also exactly what happened, thought Robie.
