Dr. Eric "Rick" Decker arrived in Oakdale in 2003 after meeting Susan Stewart at a medical conference and charming her. He was quickly offered a job at Memorial. Soon, several patients began to die and it was suspected, since Bob Hughes was their physician, that it was his incompetence. Bob stepped down as Chief of Staff and turned to Rick for help with some memory problems he was having. The deaths continued. Nurse Krebbs was killed and Bob asked Walker Daniels, a forensic pathologist, to investigate. Through the investigation, Dr. Gordon and Rick became suspects. Bob would not consider Rick as a viable suspect, however, even after he learned of the deaths of Rick's patients in San Francisco. Bob was then attacked and was in a coma for several weeks. Rick was attacked as well but he recovered, shifting suspicion solely on Dr. Gordon. He was found dead soon after from an apparent suicide.
Susan continued to defend Rick and he convinced her to marry him. On the day of the wedding, reporter Jeffrey Starr began asking questions about Rick's time in San Francisco. Rick murdered him because of it and then hurried the wedding forward. He drugged Susan that night and covered up the murder. Things got dicey when Alison dropped by to see her mom and mentioned that Rick had been out the night before. He convinced Susan that Alison didn't see him because he went for a job. Rick threatened Alison to keep quiet. The Oakdale Police continued their investigation and learned that Rick was suspended from medical school for flat-lining - a practice that makes a person's heart stop. Fearing he would be found out, Rick convinced Susan to come away with him because he was having anxiety attacks. Once they were away from Oakdale, he tried to drug her again but at the last second, Alison replaced the poison he would have used with water. Susan woke the next morning and saw a headline that Alison was dead and she had last been seen with Rick! Susan couldn't deny things any longer and confronted Rick, who confessed. Susan tried to run but Rick caught her and held Susan and Alison - who wasn't really dead - hostage. Chris Hughes managed to rescue them both. Rick confessed to police but said he really was in love with Susan. Rick was eventually committed to a mental institution.
At the mental hospital, Rick began to have feelings for Barbara Ryan, who had also been committed. He wanted to kill her but decided he was too in love with her for that. Barbara liked him, too, and helped him plot his escape so they could be together. Rick tried convincing a janitor to help them but he turned them down. Barbara told him to steal the janitor's keys anyway. A security guard became suspicious of them and separated the pair. Rick began to suspect that Barbara was using him and the night of their planned escape, he kidnapped her to the Old Mill. As they were struggling, Will arrived on the scene. He saved his mom and knocked out Rick.
Rick returned to Oakdale as a prisoner, helping law enforcement solve cases with his medical expertise. Rick helped the authorities figure out who was really responsible for Sofie Duran's death. He was sent back to prison after solving the case but wasn't finished. Strange jewelry and perfume gifts began appearing around Oakdale and it turned out that Rick had poisoned the gifts and sent them to people in Oakdale. He extorted money from Barbara and Paul after poisoning Meg. Chris caught on to the scheme and developed an antidote after he was infected. Rick kidnapped Alison, also infected, from the hospital but Chris followed them to the roof and captured Rick.
