At one point, Alvin had served in the U.S. Army as part of a Special Response Team in Italy, implied to be the 173rd Airborne Brigade Combat Team. It is revealed that he had seen some action in Italy while serving there.

Later on, he joined the CPD working alongside Sergeant Hank Voight, Jimmy Shi, and Ruzek's father Bob. Alvin and Voight shared a close partnership and friendship.

Season 1Edit

It is revealed in Now Is Always Temporary, that Alvin had an estranged relationship with his wife, who had made him move into the garage. Despite the tension in his marriage, Alvin still loved her (vice-versa) and maintained a close relationship with his daughter, Lexi. When Lexi was blamed for having marijuana in her locker (stored there by a boyfriend), Alvin was quick to help his daughter out. Even though she was suspended from school, the two had a father/daughter dance in the garage.

When an ill-fated party ended in a gang member's shooting death, Lexi was the only witness. Alvin tried to prevent Lexi from becoming a witness as it would endanger her life. However, when the shooter refused to confess, Lexi volunteered.

During Conventions, Alvin tells Halstead that he served in the army and Halstead tells him of his service in the Rangers.

In My Way , Alvin talks to Antonio about how it must be hard for him to be in the same room with a gangster who abducted his son. Antonio lashes out at him for mentioning this because the monster was responsible for killing his partner and putting his family in peril. The next day, Antonio apologize to Alvin for his outburst while Alvin lets it slide because he can understand that and they make up.

As of The Docks, Alvin finds Antonio has survived the shot but is critically wounded. Alvin and Voight want to kill Pulpo instead of capturing him, since he hurt their comrade. After Pulpo is captured, Alvin and Hank prepare to get revenge on the gangster by dropping him in the lake. The pair are beat Pulpo severely and chain him to cement. However, Jay arrives to stop the two detectives them, moments before sinking Pulpo into Lake Michigan wearing a "Chicago necklace" - chains around his neck linked to cement blocks. Jay pleads to Voight to not do it and the Sergeant refuses to give in - until Olinsky (has an epiphany) sides with Halstead. Pulpo will receive his day in court. The intense aftermath sends Olinsky back to the arms of his wife - he wants to restart their marriage - and leads Voight to a bar, where Halstead joins him. Voight buys his round and surprises Halstead with encouragement - he respects the detective's conviction, even though they don't always see eye to eye.

Season 2Edit

Antonio told Ruzek that Olinsky already had full pension but refused to retire.

In Born Into Bad News , Alvin is contacted from a woman named Linda Sovana from his past undercover assignments who is hostile to him because he used her. At the end, it is revealed the Alvin has another daughter named Michelle Sovana born from his affair with Linda. Michelle contacts Alvin from the juvenile hall center, asking for help. He is quite shocked to learn this and fall silent.

Season 3Edit

As of Life is Fluid, Alvin is still stunned at having another child, though decided to bond with her, since she needed him. Telling Trudy about this, Alvin is able to pull strings and get Michelle out of jail. Michelle appreciates his acts and asks for money, to which he gives her $40. She then promises to keep in touch with him.

During Natural Born Storyteller, Alvin is once more approached by Michelle who in many ways tries to reject but also tries to bond with him. Not wanting to play mind games with her, Alvin tells her that he is trying and if she allows him in, then they can have a better start.

In Actual Physical Violence, at dinner with his family, Alvin reveals the existence of his other daughter born from his affair while on assignment. They are stunned to hear this with Meredith even telling him that he needs to leave while Lexi is reduced to tears.

In Debts of the Past, Alvin talks with Antonio about his new development while the latter was surprised to learn that Alvin has a new daughter. Alvin is approached by his wife at work who encourages him to get a paternity test to confirm whether Michelle is really his daughter before he makes it a irreversible effect on their family. Alvin considers her words. After being told by Greg how to do the test he goes to meet with Michelle, who was training under Antonio at his training center. He arrived at the center where he finds Michelle training, after Michelle conveniently leaves her mouthguard which contains her saliva Alvin use it to get the test.

Before leaving home he gets to his car, he has a since that it may have been rigged so he decides to take a taxi. At the precinct it was confirmed that his car was indeed rigged to explode because of a pipe bomb being placed underneath. Culprit is revealed to be a man who was previously put away by Hank and Alvin years ago and believe that they were responsible for stealing his money and Alvin is upset that Hank would accuse him of doing such a thing when he went to pay Hank and Camille back the money he borrowed. It is then revealed that the beef was one of the low level grunts who used the money to support his family. When the gangster is found they use them as bait to lower the crime lord and are able to apprehend him. Alvin quickly stop Hank from trying to kill the crime Lord because it wasn’t the right thing to. At the end, the DNA results for Michelle come back in but it’s never confirmed whether she is his daughter because he threw away the paper.

Season 4 Edit

The season started with the transfer of Kim Burgess to Intelligence after Antonio took up a job as an investigator with Peter Stone. Kim was paired with Alvin by Voight, and he did not take a clear liking to her. She is happy and excited to work with him but he often brushes her off. Platt tells Kim that she thinks it's because he doesn't think women work well in the force because he was there when women were first allowed to join in 1974. Kim is surprised by this but continues to try and earn his trust and take his criticism, something he keeps doing However, he later tells Voight he doesn't work to with Kim because she's too bubbly and he knows the job will "rip her heart out" and he doesn't want to be there when it happens. Voight says she's very good at her job and she's earned her chance to figure that out for herself. Olinsky continues criticising Kim and at the end of her first shift, asks her why she thinks she deserves to be in Intelligence when there are others more deserving of the job. She tells him of her arrest records and achievements, to which he replies that good detectives don't boast. She is irritated and tells him she does and he should be prepared for her.

In a later case, Olinsky and Kim end up trapping themselves in a case after Kim failed to pursue a suspect who'd given the wrong number. She apologizes and he says she should because it was her fault. She is angered and Olinsky again criticizes her. However, on a pursuit on foot, Olinsky ends up in the woods and one of the suspects pulls a gun and is seconds from shooting him when Kim tackles him and saves Olinsky. Olinsky thanks her in the end.

In Emotional Proximity, Alvin's daughter, Lexi died in the hospital after a fire at the Kimball Factory. A crossover with One Chicago showed Alvin asking Chief Boden to go back in for Lexi. They do and recover her, but Will Halstead tells Alvin she has burns on 60% of her body. They are hopeful until Lexi goes into heart and organ failure, after which Will tells Alvin she won't make it. Lexi dies with Alvin and her mother by her side at the age of 19. Alvin is angered and goes back to work to find out who did this. When they find the man, Alvin is clear that he wants to kill the man. Voight stops him.

Season 5 Edit

Olinsky's DNA is found on the body of Bingham, the man who Voight killed in revenge for Bingham killing his son Justin. Olinsky is later arrested for murder, and while in prison is stabbed by an inmate.

In Homecoming, Olinsky died in hospital, after significant blood loss from the stabbing. He is avenged by Voight, who shoots and kills the man responsible for setting up Olinsky's death. Despite Meredith not wanting him to attend the funeral, Voight secretly attended and paid respect to his longtime friend and partner.

Season 6 Edit

This series of events, unfortunately, raises an imminent suspicion unto Voight, during which he is temporarily discharged for the shootout. Olinsky's reputation, however, remains tainted, even after his funeral. When Voight returns to duty, after finding a security video that proves the shot was justified, the first thing he asks for from Deputy Katherine Brennan is a letter of exoneration for Olinsky; this is not signed until Bad Boys.

Physical appearance Edit

Olinsky was typically seen in a casual suit jacket, jeans and a shirt.

He was hardly seen without a cap or hat of some sort. Underneath this cap, he is shown to be balding.


Alvin has an unwavering loyalty to his closest friend and longtime partner Voight and will do whatever he asks even off the books. His loyalty was well placed because Hank defended him many times. Hank also attended Al's funeral.

Al was estranged from his wife, largely due to the stress of his job often making him detached. He still loves his wife and stayed in the garage to be near her. Al also loves his daughter Lexi doing his best to make time for her and I hesitating to come to her defense when she needed him something she appreciate it. He was very sad when Lexi died in a fire nearly attacking the man responsible until he was stopped by Hank. When he discovered he had another daughter named Michelle, he was quite shocked but did his best to make a spot for her in his life. Even though he got a DNA test for her, he chose not to see the results deciding to be a father figure to her to better her life at the cost of being separated from his family.

Alvin had a rocky relationship with some of those in his unit. This is largely due to most of my them being inexperienced and cocky. However, he proved that he cared for them because Alvin came to their aid in many ways. At his funeral, they all mourned him

He was an expert at undercover stakeouts. His dedication was evident by the fact that he wore adult diapers to make sure he didn't miss his targets. This began after a particularly nasty incident where a B&E team got away when he went to relieve himself.

    • Unlike most police personnel, he holstered his gun in the "12 O'Clock" position, rather than by the hip.
    • He also carried a Smith & Wesson 36 in an ankle holster as a backup.
