WARNINGS: MENTIONS OF MURDER

Olivia Benson was not used to strange letters on her desk. They came, but rarely, and when they did come, they were never good.

"Olivia, a letter came for you!" Cragen called, dropping a manilla folder on her cluttered desk.

"Thanks, Captain," she responded.

"Who's it from?" Elliott asked, sipping his coffee.

She shrugged. "I don't know. I wasn't expecting anything."

She pried the letter open with her fingernails and pulled out the first of several papers, frowning.

"What is it?" Elliott questioned, noticing her change in expression.

"It's a missing poster from five years ago. Chance Walker," she replied, displaying the black and white paper.

Missing was scrawled across the top in bold. The picture of a boy around eleven with a bright smile stared up at her.

"Chance Walker?" Cragen said, looking up at the name. "I remember that case. Blonde boy, eleven years old, goes missing without a trace. He was in a foster home with two other kids and a single foster father. Foster father and brother were on a bike ride because the boy was new to the home, and the man wanted to get to know him a bit better. Since Chance had a disability and the other foster brother was recovering from a broken leg, they left them with a babysitter. They came home, no one was there. She was arrested and killed herself in jail three weeks later."

Elliott frowned. "How do you remember so much about the case?"

"There was something strange about the case," Cragen explained. "I didn't think the babysitter did it, but there was no other evidence. No witnesses."

"What about the other foster kid?" Munch wondered.

"He ran away from the hospital. Some thought he did it, but both boys were eleven, and the runaway was much smaller than Chance. Even if Chance had a disability, he would've been able to get away from the kid easily."

"What was his name?" Fin asked.

"Leo Valdez," Olivia said before Cragen could open his mouth.

She displayed another paper, which contained two side by side photos.

One was of an eleven year old boy with a black eye and a split lip, his eyes dark, as though something behind them had broken.

The second was of a sixteen year old kid, laughing and smiling. The picture was zoomed in, but he was holding hands with someone, probably his girlfriend.

Despite the age difference, the boys were obviously the same person.

Above the photos, the name Leo Valdez was written, and below them was a message:

Speck's a liar. Find the runaway. He'll tell you everything.

THE HOME OF JORDAN SPECK

FORMER FOSTER FATHER OF LEO VALDEZ, CHANCE WALTER, AND CHAD CARRACE

Olivia knocked on the door of Doctor Jordan Speck, who opened it shortly after.

Jordan was an inch shorter than Elliott with neatly combed brown hair and blue eyes. His nose was short and thick, and his skin was pale; he was dressed in a gray T-shirt and jeans.

"May I help you?" He asked, politely.

Elliott and Olivia flashed their badges.

Jordan blinked, clearly not expecting them.

"Come on in, Detectives," he instructed, stepping aside and allowing them in. "What can I do for you?"

"We were wondering about an old foster child of yours. Leo Valdez?" Elliott said.

Jordan's eyes widened. "That's a name I haven't heard in a while. What do you need to know?"

"Have you heard from him?" Olivia interrogated.

"Not since he ran away after... after Chance," Jordan choked out, almost unable to force out Chance's name.

"Is it true that Leo was there the night Chance disappeared?" Elliott asked.

Jordan nodded. "When we got home, Chance and the babysitter were gone. Leo was sitting in the corner, trembling with this glazed look in his eye. She drugged him, and then, although I can't prove it, I think she killed Chance right in front of him. Something terrible had to have happened for him to have such a... traumatized look in his eye."

Jordan's eyes were far away, but as he finished the horrible tale, he shook his head and brought himself back down to earth.

"Does Leo have anyone he would go to?" Olivia continued. "Friends, family?"

"Not that I know of," Jordan responded. "His mother's dead; father left before he was even born; remaining family threw him to social services, thinking the eight year old kid killed his mother. After that, he was tossed from foster home to foster home, always running away. When he came to me, he had a black eye and a split lip from getting jumped while living on the streets."

Olivia nodded. "Thank you."

"Well, what now?" Olivia questioned. "No other leads."

Elliott shrugged, sighed, and picked up the side by side photos of Leo Valdez.

"Hey, Liv," he suddenly said, realization creeping into his voice. "Look in the background."

He showed her the photo, and she stared hard at the fuzzy background.

"Chaplan's Café," she said. (Totally made up place)

A new lead.

CHAPLAN'S CAFÉ

OWNED BY CHRIS CHAPLAN

"Have you seen this boy?" Olivia asked Chris Chaplan as she showed him the photo of sixteen year old Leo Valdez.

Chris Chaplan was a short, chubby man with quite the gut growing. He wore an apron, and he was in his fifties with gray hair threading the sparse amount of brown curls left on his head. He seemed friendly, and his smile was bright.

Chris examined the photograph.

"Yeah," he finally said. "He came in here last Friday with his girlfriend. Rather pretty girl; her name was Calypso, like that Greek goddess. Said it was her first time in the States, so he was taking her all over New York."

"Did he mention where they lived?" Olivia asked.

"No, but I did overhear them talking about their plans. I think they have plans for months. He said they were going to Time Square the next day."

Elliott nodded. "Good. Thank you."

AEROPOSTLE, TIME SQUARE

"There's dozen of stores here," Elliott muttered. "There's no way we'll get through them all."

Olivia shrugged and approached the front desk in the store Aeropostle.

"Excuse me, sir? Do you know this boy?" She asked the teenage boy behind the counter.

He nodded. "Yeah. He's right there."

He pointed over Olivia's shoulder, and the detectives turned to see that Leo Valdez stood beside a pretty girl closer to the door as she rifled through clothes.

"That was fast," Elliott muttered, not believing their good fortune, before he and his partner approached the couple.

"Out of everything in New York, I cannot believe you keep coming back to this store," Leo laughed.

The girl smiled. "Hey, in my defense, yesterday, I was wearing a Greek dress. And you thought you were behind in fashion, Mr. Suspenders."

"I'll have you know suspenders are very fashionable, Sunshine," Leo chuckled.

"Excuse me?" Elliott interrupted. "Are you Leo Valdez?"

The teenage boy immediately became suspicious.

"Who wants to know?" He asked.

Elliott flashed his badge.

Leo gulped. "You're not dragging me back to social services, are you?"

Olivia smiled and shook her head. "No. We're here to ask you about Chance Walker."

Leo paled. "Calypso," he addressed the girl. "Head back to camp. I'll call Annabeth later and give you an update."

"But, Leo-"

"Calypso, I promise I will tell you everything. Just not right now, okay?"

Calypso nodded and left the store.

"How about you come back to the station?" Olivia asked.

"I will only answer your questions if you promise not to force me back into a foster home."

Olivia nodded. "We won't involve social services."

Leo nodded and followed the detectives to their car.

Olivia slid the papers across the table to show Leo.

"Do you know who sent these?" She asked.

Leo didn't even hesitate. "Chad. He's the only one, other than me, who knows."

"Knows what?"

Leo swallowed. "I don't want to talk about it."

"Leo-"

"No. I've gotten my life together. I'm off the streets; I have a girlfriend, friends, a family, and if I have to remember that one night, I'll have to remember everything. Whenever the memories start coming back, everything falls apart. I can't have it fall apart again," Leo stressed.

"Leo, what about Chance? He was never found. You can get justice for him," Olivia said.

Leo seemed to consider this for a moment.

"She didn't kill him," he finally voiced.

Olivia blinked. "The babysitter."

Leo smiled, faintly. "Sarah. The highlight of our time with Him was when Sarah came."

"Him? You mean Jordan Speck?"

Leo flinched at the name, but he nodded.

Olivia, slowly, leaned forward, her eyes concerned. Realization was beginning to dawn on her.

"Leo... what did he do?"

Leo shifted in his chair. "He... he killed him."

Oliver was taken aback. She'd suspected, but to hear Leo tell her so quickly was slightly shocking.

"Why?" She whispered.

"He didn't mean to," Leo murmured. "He hit Chance, and Chance hit him back. They started fighting, and he... he snapped Chance's neck. He panicked, threatened to kill Chad if Sarah and I didn't go along with the plan, and vice versa with Chad. I was scared. I ran away from the hospital. I didn't want to go back to Him."

Tears rolled out of Leo's eyes and down his cheeks.

"I left Chad with a monster," he murmured. "Oh, gods."

Olivia reached forward and grabbed Leo's hand.

"Leo, I'm sure you'll be glad to know that Jordan Speck stopped fostering kids after that. Chad was moved into another home."

"Can I see him?" Leo asked.

"We're going to find him, and then, yes."

"Can I call my friends, just to... explain?" Leo asked.

Olivia nodded. "Of course. I'll get you a phone."

Olivia left the Interrogation room and found Cragen and Elliott outside.

"There's more to the story," she said right off the bat. "I don't think he's lying, but he's definitely not telling the whole truth."

Cragen nodded. "I'm gonna have Huang interview him. Whatever happened, it messed that kid up, even if he's good at hiding it. Let's see if Huang can get him to talk."

How was the first chapter?
