Damon Porter - David Chow

David Chow first appeared on January 9, 2007, portrayed by Vincent Irizarry, investigating the murder of ex-fiancee Carmen Mesta. Later marrying Nikki Newman, David was a mobster hit man who later died in a fatal car accident with Sabrina Costelana.

Casting
Irizarry's casting for the role was announced by multiple sources in November 2006. He taped his first scenes on November 21, 2006, and was to "tackle the role of David Chow, a character who is connected to the recently-murdered Carmen Mesta." In 2008, it was reported that Irizarry was to exit The Young and the Restless. After the announcement of his departure, news broke that Irizarry was to reprise his All My Children alter-ego, David Hayward.

History
David Chow was a savvy political operative who arrived in Genoa City to avenge the murder of his former fiancée, Carmen Mesta. He quickly zeroed in on Drucilla Winters as the chief suspect in her murder, and gave a tape of a heated argument between the two to the press, which elevated further suspicions on Dru, who was extremely angry with Carmen for her involvement with her husband, Neil Winters. David waged an ugly campaign to drive Dru crazy by hiring Carmen's look-alike cousin, Ines, to appear around town and haunt Dru. After Jana Hawkes confessed to killing Carmen, David and Ines came to Dru's competency hearing to prove her sanity.

Meanwhile, Victor Newman made David a lucrative offer to work on Jack Abbott's Wisconsin state senate campaign. David then released a video of Jack's competition, Victor's then-wife Nikki Newman, stripping in order to make her look bad, leading to his firing. Nikki saw this move as an opportunity to get David to work for her, and she then had two campaign managers in the forms of him and Karen Taylor. David and Nikki connected, even after her son Nicholas Newman was hurt by him. When Victor was out of town looking for his estranged son, Nikki and David shared a kiss, which unbeknownst to them was recorded by Sharon Abbott and Phyllis Newman. Victor discovered their kiss online, which caused more marital problems for the couple and ruined Nikki's senate campaign. She lost the election to Jack, but continued to see David afterward.

Soon after, Nikki hired David to work for her company, N.V.P. Following an accident, Nicholas was presumed dead and then found alive, and an accident left Nikki's daughter Victoria Newman in a coma. These events brought Nikki and Victor back together, and Nikki insisted that David get out of her life. Evidently, this didn't last long as her reunion with Victor was shattered, and she and David became engaged. However, Nikki lost N.V.P. in her divorce settlement. Later on, David and Nikki became co-CEOs of Jabot Cosmetics. Victor warned her about David's eventful past, which included three previous marriages. He believed David was after Nikki's money, but she didn't listen to Victor and they continued their engagement.

Walter Palin then arrived in town, a loan shark who David paid off his debt to. Walter was the only person who knew David's true identity, "Clark." After a heated fight between the two men, David agreed to tell Nikki about his gambling problem and debt, which she chose to pay off and tried to commit him to help with his addiction, which he refused. However, Brad Carlton set David up to relapse with the help of Skye Lockhart as he did not believe David was worthy of his CEO position. Skye ended up taking money from David in a poker game.

Victor became engaged to Sabrina Costelana, which made Nikki jealous, and she and David thus eloped to Mexico to "one-up" him. Paul Williams then investigated David's previous marriages, which revealed that both of them were extremely wealthy and had been met with untimely, suspicious ends. David's third wife Bitsy Hartford told Paul that he got away with killing his first wife Janelle by saying she committed suicide after he cheated on her. Paul then met Mina King, the daughter of David's second wife, Angela Perkins, who, convinced that he murdered her, told Paul that David told Angela to cut her out of the will, leaving him the sole beneficiary, and that he cut the breaks in her car, causing the fatal car accident that killed her. When Paul confronted David with this information, he said Mina was cut from the will because of her drug addiction. Eventually, David had no choice but to tell Nikki of his eventful past.

David said Janelle died of a sleeping pill overdose whilst they were traveling the world on humanitarian missions, and that he was never charged for her murder. Angela supposedly crashed her car into a telephone poll and died after a heated argument with him, and Bitsy was supposedly extremely paranoid which lead to an affair with Carmen, a divorce and allegations against David.

Brad continued to feed his gambling addiction, debts began to appear again and David became desperate for money. Eventually, he asked Nikki for a divorce as he feared he'd gamble all her money away. Nikki refused to give up on him, however Paul continued to search through his past and discovered his real name was Angelo Sarafini, and was in fact a mobster hit man for Walter, or Tony Amato. He was then involved in the death of Ji Min Kim acting on Walter's behalf, and then Mina died under suspicious circumstances. Learning of all these events, Nikki left David and planned to divorce him.

At a charity gala, David spiked Nikki's drinks with dangerous amounts of morphine, however was rescued and brought to hospital before it affected her. At the same time, Sabrina insisted that she and David ride home together as she didn't feel well. Their limousine crashed; Victor got a call about a Mrs. Newman in distress and arrived on the scene, expecting it to be Nikki when in reality, it was Sabrina. Victor was confused to as why she was with David, but they both ended up dying from their severe injuries. Later revelations state that Walter was responsible for the accident. After his death, David was continually suspected in the murder of Ji Min Kim and then Skye, which proved to be a fake-out.
