History Recap / LawAndOrderS19E2Challenged

Rick Devon is killed outside the public toilet in a park known as a hotspot for drug dealers. From a key that was lost in the toilet, Lupo and Bernard trace Diego Cardenas: a former gang member who's now in charge of a residential centre for those with mental disabilities. Cardenas' story of when he was in the park doesn't add up, but he's subsequently killed by gangsters "Big Chuck" and "Momo." The detectives figure out that Cardenas was trying to protect Pete Harris - one of the residents, who's now missing. Pete was the victim's co-worker and they were working together on the night of the murder.

The detectives track Pete down to an upstate hospital where Cardenas had him transferred. Pete says that he and Rick walked home after work, and Pete stopped to use the toilet; when he came out, Rick had been killed. Big Chuck and Momo are charged with murder after Pete identifies them as present at the scene, but they insist they only killed Cardenas - not Rick. Through questioning Pete, the detectives discover that he is actually Rick's older brother who was given up for adoption because of his disability. Rick had recently traced him, but now all documents relating to the adoption are missing from Rick's files.

The Devons request a reunion with Pete, which becomes tense. Pete's brother mentions that another brother, Ted, said Pete will only drink out of a plastic bottle. Since plastic bottles didn't exist when Pete was adopted in the 1960s, Cutter and Rubirosa realize Ted must have seen Pete more recently. Later, Pete says that when he was in the park toilets, he heard Ted yelling at Rick outside. Ted is charged with murder but this will be difficult to prove because the severely disabled Pete is the only witness. Furthermore, Pete's now moved back in with his family, who may affect his testimony.

On the stand, Pete suddenly changes his story and says ''he'' killed Rick accidentally. The [=DA=]s know this is an obvious lie, but Cutter insists Pete be arrested for murder. He then tells Pete's parents that Pete is likely to be convicted and jailed for life. Mr. Devon refuses to believe this, but Mrs. Devon breaks down with guilt over abandoning Pete. She implicates Ted, and he confesses to killing Rick. Ted states that he didn't want his parents' lives to be disrupted by Pete returning. After the court hearing, Cutter and Rubirosa witness Pete going home with the Devons, who finally seem happy to have him back.
