Part 15
My heart slammed against my ribs so hard I thought my chest was going to split open right there in the surveillance room.
My own brother hadn't just helped poison my wife before the wedding—now that Helen had survived the first attempt, he was paying an insider on the tenth-floor oncology unit fifty thousand dollars in cash to walk into her isolation room after midnight and finish the job.
"Get on the radio with Northwestern Hospital Security right now!" Detective Sergeant Kowski barked, already sprinting out the door toward the elevator bank while Special Agent Sarah Miller keyed her encrypted federal mic.
Within forty minutes, we were locked inside the hospital director’s security command center in the basement of Northwestern Memorial. It took the hospital’s human resources computer less than ninety seconds to cross-reference the night-shift respiratory therapy schedule on the tenth floor against the name Greg.
There was only one: Gregory Halstead, a thirty-four-year-old respiratory therapist who had worked the oncology telemetry unit for three years. When Agent Miller’s forensic analysts ran Halstead’s Social Security number through FinCEN and Cook County court records, the connection popped up immediately. Six months ago, Halstead had filed for Chapter 13 bankruptcy protection after racking up $110,000 in high-interest gambling debts with the exact same offshore sports-betting syndicate Paul had been wiring money to.
"We arrest him the second he clocks in at 7:00 PM," I growled, my hands trembling with rage as I stared at Halstead’s employee badge photo on the monitor.
"No, David," Detective Kowski said firmly, placing a heavy hand on my shoulder. "If we grab Halstead at the time-clock in the lobby, all his defense lawyer has to say is that Paul was paying him back an old gambling debt and he never intended to hurt your wife. In Illinois, to nail both Halstead and your brother for Conspiracy to Commit First-Degree Murder with zero bail, we need Halstead taking a substantial physical step toward the crime on camera."
At 8:00 PM, under the cover of a routine radiology transport, four armed hospital security officers and two nurses quietly moved Helen out of Room 1014 down to a locked private cardiac ICU suite on the sixth floor. I stood outside her new door with two uniformed DuPage County deputies who had strict orders to shoot anyone who wasn't on the surgical team.
Upstairs in Room 1014, the FBI technical crew went to work. They placed a weighted medical training mannequin under the heated blankets, wrapped sterile white gauze around its head to match Helen’s bandages, and hooked the central IV pump up to a closed saline bag beneath the sheets. Then, Detective Kowski and two tactical officers in dark hospital scrubs stepped into the negative-pressure isolation anteroom right next to the bathroom, clicking off the lights behind the one-way observation glass.
Following Paul’s expectations, I walked out of the hospital’s main lobby at 11:50 PM in full view of the street cameras, got into my truck, and drove two blocks away, where I sat in the back of an unmarked FBI command van staring at the live infrared feed from Room 1014.
At 1:18 AM, the hallway outside Room 1014 went quiet.
On the monitor, Gregory Halstead walked softly down the corridor pushing a respiratory nebulizer cart. He paused outside the nursing station, waited until the night charge nurse walked into the medication supply room down the hall, and then swiped his override badge on the isolation door of Room 1014.
He didn't turn on the room lights. Guided only by the green glow of the heart monitor, Halstead stepped up to the left side of the bed. He reached deep into the front pocket of his blue scrub pants, pulled out a pre-filled twenty-milliliter syringe of concentrated Potassium Chloride—a drug that stops the human heart within ninety seconds and leaves almost no trace beyond a natural cardiac arrest spike in cancer patients—and uncapped the needle to screw it into the main IV line leading to the chest port.
Before the metal tip even touched the plastic valve, the bathroom door burst open.
Detective Kowski hit Halstead square in the ribs like a linebacker, slamming him face-first onto the linoleum floor while two federal agents pinned his wrists behind his back and snapped steel cuffs around them. The syringe skittered across the floor into an evidence marker.
"Police! Don't make a sound!" Kowski hissed right into Halstead’s ear as the therapist began hyperventilating and sobbing so hard he wet himself right there on the hospital floor.
When they dragged Halstead into an empty conference room down the hall ten minutes later and told him he was looking at natural life in a maximum-security penitentiary for attempted murder of a disabled oncology patient, he folded like a cheap lawn chair in less than four minutes. Sobbing uncontrollably, he signed an emergency proffer agreement and agreed to help the FBI close the trap on Paul.
At 1:42 AM, with Agent Miller holding the burner phone in front of his face, Halstead sent a single pre-scripted text message to my brother Paul:
I couldn't use the KCl because a nurse walked past the window, so I injected a slow-release hepatotoxin straight into her IV hydration bag. It’ll shut her liver down gradually over the next 72 hours. The doctors will think it’s chemo failure by the weekend. Leave the $50k in the locker at the gym.
Ten seconds later, three dancing dots appeared on the burner phone screen, and Paul’s reply popped up:
Perfect. Even cleaner that way. David is signing the entire company and the family trust over to us on Friday night at 7 PM at the Drake Hotel. By the time the hospital calls him to say she’s coding, the ink on the contracts will already be dry.
