Who Are the Main Suspects in ‘The Residence’?
After taking a break to search for a rare bird called the Giant Antpitta, Cordelia returns to the White House. Her close friend, Chief of Police Larry Dokes (Isiah Whitlock, Jr.), had earlier ruled the case as a suicide. However, new evidence forces the investigation to reopen.
Cordelia meets with several White House staff members to discuss the events leading up to A.B. Wynter’s death. She carefully studies their reactions and remains uncertain about the murderer’s identity at first. However, she quickly narrows her list of suspects.
The people under suspicion include:
-
President Perry Morgan (Paul Fitzgerald)
-
First Gentleman Elliott Morgan (Barrett Foa)
-
Tripp Morgan (Jason Lee), the president’s brother
-
Jasmine Haney (Susan Kelechi Watson), the deputy usher
-
Marvella (Mary Wiseman), the executive chef
-
Didier Gotthard (Bronson Pinchot), the pastry chef
-
Sheila Cannon (Edwina Findley), an enthusiastic butler
-
Lilly Schumacher (Molly Griggs), the social secretary
-
Elsyie Chayle (Julieth Restrepo), a housekeeper known for her honesty
-
Bruce Geller (Mel Rodriguez), an engineer
-
Patrick Doumbe (Timothy Hornor), known as the “Third Man”
-
Harry Hollinger (Ken Marino), a difficult and unpleasant character
Cordelia instructs her reluctant partner, FBI Special Agent Edwin Park (Randall Park), to observe the suspects closely. She tells him to look for “the blink.” Just like a mockingbird flashes its wings before catching its prey, the true culprit will reveal themselves by reacting strongly during her investigation.
Who Committed the Murder?
Through a series of clever observations, Agent Park finally sees the guilty reaction Cordelia is looking for. The murderer is none other than Social Secretary Lilly Schumacher.
Lilly had been secretly stealing money for personal projects, and A.B. Wynter had collected proof of her crimes. He planned to expose her, which would have ended her career. In a desperate attempt to save herself, Lilly acted quickly.
She tore a page from his journal that contained evidence of her misdeeds. That single page appeared to be a suicide note. This gave her an idea—if A.B. Wynter died, her secrets would be safe, and she would also have the freedom to redesign the White House however she wanted.
Lilly then planned the perfect way to make his death look like a suicide.
How Did Lilly Schumacher Commit the Crime?
Lilly arranged a private meeting with A.B. Wynter. She pretended to feel sorry about their earlier argument and invited him to talk over drinks. Since she was in charge of the “Conscious Landscaping” project at the White House, she had easy access to paraquat, a dangerous herbicide.
She intended to mix the poison in a drink, but the glass she planned to use broke. Instead, she poured the paraquat into a nearby decorative vase. Then, she tricked the Secret Service by imitating First Gentleman Elliott’s voice and requesting that the second floor remain empty for their meeting.
Meanwhile, Elsyie Chayle was arguing with A.B. Wynter over a lie she had told on her résumé. After Elsyie left, Lilly entered the room with two glasses of Scotch—one of them poisoned. She placed the torn journal page back in A.B.’s pocket to make it look like a suicide note.
A.B. Wynter took a sip of the Scotch, but he quickly realized something was wrong. He spat out the drink and poured the rest onto some nearby flowers. Lilly, realizing her plan had failed, panicked. She threw a vase at A.B., but she missed. In desperation, she grabbed a heavy clock from the mantel and struck him, killing him instantly.
To hide the weapon, Lilly placed the clock in a hidden passageway between the Blue and Yellow Oval rooms. She then sneaked through the Treaty Room, went down the Grand Staircase, and rejoined the dinner as if nothing had happened.
How Was the Murder Scene Covered Up?
Bruce, the engineer, discovered A.B. Wynter’s body soon after the murder. Elsyie also arrived at the scene around the same time. Both of them assumed the other was responsible. Bruce, who cared deeply for Elsyie, decided to cover up the incident.
He carried the body upstairs to Room 301, which was supposed to be under renovation. To make the process easier, he temporarily placed A.B. Wynter’s body in the Lincoln Bedroom.

Later, Tripp Morgan, who had passed out in Room 301 after drinking too much at the dinner, woke up to find the body next to him. Fearing that he would be blamed, he moved the body again—this time to the Game Room. He then took a knife from Chef Gotthard’s kitchen and made it look like A.B. Wynter had cut his own wrists.
Detective Cupp’s investigation continued, and Lilly began to feel nervous. She knew she had to eliminate all evidence. To make sure no one ever found the murder weapon, she once again impersonated Elliott and ordered Deputy Usher Jasmine Haney to seal the hidden passageway.
She also used the opportunity to redecorate several rooms, disguising her actions as part of her remodeling projects.
Why Did Lilly Schumacher Kill A.B. Wynter?
Lilly’s hatred for the White House and its staff drove her to commit the crime. She saw the building as an outdated institution filled with people she did not respect. A.B. Wynter, who had spent his life preserving the traditions of the White House, represented everything she disliked.
By eliminating him, she aimed to take full control and redesign the White House as she saw fit. Her actions were selfish, but they were also calculated. She manipulated people and situations to cover her tracks.
Ironically, the mistakes and misjudgments of others allowed her to remain undetected for a while. But in the end, she could not escape the sharp mind of Detective Cordelia Cupp. The detective’s birdwatching skills and keen observation led her to the truth.
Netflix’s The Residence delivers a brilliant mix of mystery and comedy. The show keeps viewers engaged with unexpected twists and unforgettable characters. Fans of detective stories will enjoy Cordelia Cupp’s journey as she uncovers the truth behind one of the most intriguing cases in the White House.
The Clever Detective Who Solved the White House Murder
Detective Cordelia Cupp (Uzo Aduba) proves her brilliance in The Residence, Netflix’s latest mystery series from Shondaland. This thrilling show brings humor, suspense, and clever detective work into a high-stakes investigation.
The murder of White House Chief Usher A.B. Wynter (Giancarlo Esposito) shocks everyone, and the list of suspects is long. Cordelia carefully studies each person’s actions, uncovering secrets and lies that make the case even more complicated.
After stepping away from the investigation for a short birdwatching trip, Cordelia returns with fresh determination. She knows something is off, and she refuses to believe that A.B. Wynter took his own life. Instead of blindly trusting reports, she digs deeper.
She gathers a group of White House staff members and starts piecing together the events leading up to the crime. She watches their reactions closely, searching for any small sign of guilt.
Her patience and sharp thinking led her to the true killer—Social Secretary Lilly Schumacher (Molly Griggs). Lilly had been stealing money for her personal projects, and A.B. Wynter had collected proof of her crimes. He planned to expose her, which would have destroyed her career. Desperate to protect herself, Lilly saw only one way out.
She tricked A.B. Wynter into meeting her privately, pretending she wanted to make peace. She poisoned his drink with a dangerous herbicide, but he realized something was wrong before drinking too much. When he tried to stop her, she grabbed a heavy clock and struck him, killing him instantly. She quickly hid the murder weapon and escaped without anyone noticing.

However, the scene became more confusing when other White House staff members unknowingly got involved. An engineer moved the body, a housekeeper panicked, and a drunken staff member altered the crime scene, making it look like a suicide. These mistakes allowed Lilly to stay undetected for a while, but Detective Cupp saw through it all.
Using her keen observation skills, she identified the guilty party. Lilly’s plan might have worked if not for Cordelia’s determination and intelligence. The mystery, humor, and twists in The Residence make it an exciting watch for fans of detective stories. Cordelia Cupp proves that no crime is perfect—not when she is on the case.
