Shadows Disinterred: Day 19

Word Count: 114,016

Summary of Events:
Dallas succeeded in cutting himself loose, found his gun, put his clothes on, and searched Deby's room — yielding little — before he succeeded in placing Shirley and Deby under arrest for aggravated assault of a police officer and attempted murder of a police officer. He then found his keys and cell phone, but his SUV died due to lack of fuel, so he called in backup and was attacked by Deby with a kitchen knife. After recovering in hospital he interviewed the man he'd chatted with at the diner in St. Brieux some two months before, and then worked to decode 58906191.

Excerpt of the Day:
""Yes!" Dallas exclaimed.
The female officer who'd been interviewing the diner's proprietor hurried out.
"What?" she asked.
"I figured it out! It's a code made up of the digits of each victim's death date!" Dallas exclaimed.
"What is?" she asked.
"The numbers on the boxes in the basement!" Dallas exclaimed. "We have got a treasure trove of evidence down there!"
"What should we do then?" she asked.
"You've got a vehicle here, right?" Dallas asked.
"Yes," she replied.
"We need to drive down to the farm now," Dallas said. "And we need to see how many boxes of evidence we have, that will absolutely nail down a body count."
Dallas got to his feet, shoving the napkin and pen into the breast pocket of the shirt he'd picked out of his bag – which Rowland had been so kind as to bring him — and strode out to the car. She hurried after him.
"Give me the keys," Dallas said, stopping at the driver's side door.
"I can drive," she said.
"I want to drive," Dallas said.
She tossed the keys over and they climbed inside. Dallas whipped them out of the parking lot and drove back to the Pedin farm. The gate was hanging ajar, and the willows' leaves were now yellowing and falling to the ground. The farm really seemed to have changed since Dallas had last been there.
Dallas drove them around to where his SUV was still sitting, dead. The Ford was still parked in the garage — whose door was still open. The back door of the house was also ajar, as was the gate leading into the house site.
"Man, it's like I only left here yesterday," Dallas said.
He parked the car and got out, heading for the house. Stepping in the back door, Dallas looked around. The floor was clean, there was no knife, but there were some blood spatters on the wall. His blood.
Dallas shuddered and turned on the light for the basement as his fellow officer arrived at the doorway.
"This is where I was attacked," Dallas said. "They were waiting in the kitchen for me."
She shuddered as Dallas started down the stairs. He opened the door and stepped inside the basement room again. Boxes everywhere. Now to figure out how many boxes there were.
"This is a treasure trove of evidence," she said in awe as she arrived downstairs. "But the numbers don't make any sense."
"Here," Dallas said. "I'll explain. The code is the death date of each of the victims, backwards. The first pair is the year, the second pair is the month, the third pair is the day, and the fourth pair is the century. Roman numerals tell how many boxes belong to each victim."
"Except that one, it's a doubled digit," she said, pointing at a box with the first pair of numbers marking the year before the killing began.
"Let's start there, that's Al," Dallas said."
