Sean Lincecum, the older brother of former MLB pitcher Tim Lincecum, died on February 22, 2016, at the age of 37. His death was a shock and a tragedy for his family and friends, who remembered him as a loving and supportive sibling, a talented musician, and a loyal fan of his brother’s baseball career. But what was the cause of his death? And what was his relationship with his famous brother? Here is a brief overview of his life and the circumstances of his demise.

A Supportive Sibling

Sean Lincecum was born in Bellevue, Washington, on July 24, 1978, to Chris and Rebecca Lincecum. He had a younger brother, Tim, who was born in 1984. Sean and Tim grew up in a close-knit family, and shared a passion for music and sports.

Sean was the first one to learn how to play the piano and the drums, and he taught his brother how to play as well. He also introduced Tim to rock bands like Nirvana, Pearl Jam, and Metallica, and they often jammed together in their basement. Sean was also a talented singer and songwriter, and he formed his own band called The Sean Lincecum Band, which played in local venues and festivals.

Sean was also a big fan of baseball, and he supported his brother’s dream of becoming a professional pitcher. He helped Tim practice and train, and he attended many of his games. He was Tim’s biggest cheerleader and critic, and he always gave him honest and constructive feedback. He was also very protective of Tim, and he defended him from bullies and naysayers.

Sean was very proud of Tim’s achievements, and he celebrated his success with him. He was there when Tim won the Golden Spikes Award in 2006, the highest honor for amateur baseball players. He was also there when Tim was drafted by the San Francisco Giants in 2006, and when he made his MLB debut in 2007. He was there when Tim won two Cy Young Awards in 2008 and 2009, and when he helped the Giants win three World Series titles in 2010, 2012, and 2014. He was there for Tim’s highs and lows, and he always encouraged him and cheered him on.

A Personal Struggle

Despite his outward happiness and support for his brother, Sean was struggling with his own personal issues. He had a history of drug addiction and mental health problems, which affected his relationships and his career. He also had a gambling debt, which he owed to a loan shark named Spencer.

In January 2015, Sean decided to join Spencer and two other men in a plan to kidnap and rob a wealthy man named Stanley McGovern, who lived in Marmora, Ontario. Spencer claimed that McGovern owed him money and that he had a stash of cash and drugs in his home. Sean agreed to pose as a delivery person and lure McGovern to open the door, while the others would force their way in and take what they wanted.

However, the plan went horribly wrong. McGovern resisted and fought back, and the intruders brutally beat him up, leaving him with serious injuries, including a broken eye socket, a fractured skull, and a brain bleed. They also tied him up, gagged him, and threatened to kill him. They ransacked his home, but found no money or drugs. They fled the scene, leaving McGovern for dead.

An Unsolved Mystery

The police soon tracked down and arrested the four suspects, including Sean. They were charged with kidnapping, aggravated assault, robbery, and forcible confinement. Sean pleaded guilty to kidnapping, while the others pleaded guilty to various charges. Sean admitted that he was involved in the scheme, but claimed that he did not know that it would turn violent. He also expressed remorse and apologized to McGovern and his family.

During his sentencing hearing, Sean begged for mercy and asked for a lenient sentence. He said that he was sorry for any suffering he had caused, and that he wanted to change his life and be a better person. He also said that he had been clean from drugs for two years, and that he had been working as a peer support worker and a motivational speaker. He asked for a conditional sentence that would allow him to serve his time in the community, rather than in prison.

However, the judge rejected his request and sentenced him to six years in prison. The judge said that Sean’s crime was “violent and reckless”, and that he showed a “callous disregard” for McGovern’s life. The judge also said that Sean’s role in the crime was “essential and pivotal”, and that he had betrayed McGovern’s trust. The judge said that a prison sentence was necessary to denounce and deter such crimes, and to protect the public.

Sean died on February 22, 2016, just a few days after he was sentenced. He was found unresponsive in his cell at the Quinte Detention Centre, and was pronounced dead at the scene. The cause of his death was never publicly revealed, and the coroner’s report was sealed. An investigation was launched to determine the circumstances of his death, but the results were never disclosed.

His death shocked and saddened his family and friends, who remembered him as a loving and supportive sibling, a talented musician, and a loyal fan of his brother’s baseball career. His death also sparked a debate about the justice system and the prison system, and whether they are fair and effective in dealing with people who have mental health and addiction issues. Some people argued that Sean’s sentence was too harsh and that he should have been given more support and treatment. Others argued that Sean’s sentence was justified and that he had to face the consequences of his actions.


Sean Lincecum was a complex and tragic figure, who had a remarkable and troubled story. He was a supportive and protective sibling, who helped his brother achieve his dreams. He was a talented and passionate musician, who created his own music and band. He was also a troubled and desperate person, who got involved in a violent and reckless crime. He died unexpectedly and mysteriously, leaving behind a mystery and a legacy. His cause of death was never revealed, but his life was extraordinary and unforgettable. He will be missed and remembered as one of the most important and influential people in Tim Lincecum’s life.
