|“||It is heartening to see so many of you here, even in weather like this. But a lack of heart and school spirit has never been the Riverdale way. Tonight's pep rally isn't like any other we've had in the past. And we shouldn't pretend that it is. Which is why I would like to dedicate this evening to the memory of one of our brightest. Jason Blossom. We're with him tonight.||”|
|— Mayor McCoy to the crowd[src]|
McCoy is not only the powerful and fabulous Mayor of Riverdale, but also the mother of soon-to-be-world-famous Josie, of Josie & The Pussycats fame. Chic and driven, Mayor McCoy is struggling to guide Riverdale through the crisis precipitated by the mysterious death of Jason Blossom, all while making sure the town’s upcoming 75th Jubilee Celebration goes off without a hitch.
Sierra McCoy grew up in the small and close minded town of Riverdale. She attended Riverdale High School, and later proceeded to raise a family with Myles McCoy. The two of them have a daughter together, named Josie. Some time after this, Sierra became Mayor of Riverdale, and while some people are opening up, everyone in town was not so welcoming of a mayor of color.
Mayor McCoy arrived at the office to find Betty and Jughead awaiting her arrival. With the Chock'lit Shoppe on the verge of closing, the two of them sought to let Pop Tate know that the entire town was rallying behind him. They were hoping that the Mayor could make the diner a landmark or declare a day for Pop Tate in support. Unfortunately, Mayor McCoy couldn't take the risk. What if she endorsed Pop's, and next week someone else is shot, she asked. Her priorities as a Mayor and a mother was to keep the town safe by any means necessary, so if that meant the closing off Pop's shoppe, then so be it. Jughead then ambushed her with questions regarding his father's case, in which he was being shipped off to a state prison for a murder he didn't commit. FP made his own poor choices, and now it was time to deal with them. With that being said, Jughead instructed the Mayor to remember this very moment, as it is the moment that she turned her back on both Pop Tate and FP.
Another Killer on the LooseEdit
Mayor McCoy met with Sheriff Keller and the Coopers after learning that they received a letter from the supposed killer. In this letter, he confessed to the murder of Geraldine Grundy, as well as the shootings of Fred Andrews, Moose Mason, and Midge Klump. He even provided proof of these heinous crimes, ridding all doubt on whether or not he was in fact the killer they were searching for. With the letter, was Fred's missing wallet and Geraldine's glasses. In the spirit of public safety, Mayor McCoy asked that Alice not print the Black Hood's letter. However, Alice wasn't too keen on withholding the letter from the public. So, before turning the letter over to Sheriff Keller, she had made a copy of it and sent it in to print for tomorrow's front page. 
Mayor McCoy welcomed the parents of Riverdale as the Town Hall meeting commenced. She shared their concerns over the safety of their town and their children. The purpose of the scheduled meeting was to answer their questions, and if she could, to ease their minds. Sheriff Keller then took to the podium to announce that due to their tight budget, they would be putting together a help line that people could call in order to report any suspicious activity. Sounds an awful lot like the Red Circle's hotline to me, Alice interjected. In response, Mayor McCoy joined Sheriff Keller at the podium to ask if Alice had an actual question, which she did. Alice was wondering when they were going to address the real problem in Riverdale, that being the southside. All in due time, Mayor McCoy replied. But they were there to talk about the Black Hood, not the Southside Serpents or the drugs being trafficked through that side of town. She announced that the Sheriff had a plan he was putting in place, beginning with a town-wide curfew. Alice suggested that as a show of strength, they shut down Southside High, and use that money to hire more deputies, who could then protect their children.
As Alice continued to demonize the southside, Fred Andrews came to their defense, explaining that they needed to unite as a town. Only then would they stand a chance of surviving. It was then that Betty and Jughead entered Town Hall to warn everyone of the Black Hood's supposed arrival. After the lights shut off, Mayor McCoy urged everyone in attendance to stay calm and remain in their seats, though they quickly evacuated after Betty pulled the fire alarm.
Following the Town Hall meeting, Mayor McCoy and Sheriff Keller stopped by the Cooper house in an attempt to better understand how Betty and Jughead knew where the killer would strike next. Betty handed them a letter, which was sent to her by the Black Hood, along with the cipher that she had earlier turned over.
Declaring War on the SouthsideEdit
Sierra and Josie arrived at Alice's home after she discovered that Josie and several of her friends attended a party at the Five Seasons, where Jingle Jangle was in use. Sierra thanked Alice for hosting the gathering as she agreed with Alice's sentiment of coming together, so that they could deal with the children's inappropriate actions appropriately. The get-together proved to be quite informative, having learned that Reggie Mantle supplied the drugs at the party, and that his supplier was a kid at Southside High, who he believed to be a member of the Southside Serpents. Sierra then learned that not only did Josie attend the drug fueled party, but that she participated in the night's events, despite knowing that her father struggled with addiction. Before leaving with Josie, as the Mayor, Sierra announced that moving forward, her number one priority was bringing the Southside under control, even if that meant razing it to the ground or arresting every Serpent in sight.
An Affair with the SheriffEdit
Mayor McCoy and Sheriff Keller were called down to Pop's Chock'lit Shoppe after Pop Tate discovered a letter from the Black Hood affixed to the diner's door. In this letter, the Black Hood issued a test, one that would last all of 48 hours. He asked the people of Riverdale show prove to him that they were pure of heart. However, should they fail the test, and continue to sin, the attacks would resume.
That night, Sierra awaited Josie's return at the Five Seasons, which she moved herself and her daughter into because she didn't feel same at their house. Sierra confronted Josie as she entered the hotel room. She didn't want her walking the streets alone, especially with the Black Hood on the loose. She was growing so concerned that she had even considered assigning Josie a deputy, for security. Josie insisted that she didn't need a body guard. Seeking to secure her daughter's safety, Sierra told Josie that from that moment forward, she was to be in the hotel room, before dark.
The following night, with Sheriff Keller in tow, Sierra went out looking for Josie, who failed to make it home before dark. She and the Sheriff found Josie dancing in Pop's shoppe with Chuck Clayton, who the Mayor wasn't pleased to see around her daughter. "You're a damn fool", she stated. She had sent Josie several texts messages over the hours, all of which went unanswered. Chuck then interjected, explaining that he was just about to give Josie a ride home. However, Sierra didn't even want him within 10 feet of Josie.
Back at the Five Seasons, Sierra tried to make sense of Josie's recent behavior, concluding that she was merely acting out, which Sierra couldn't stand for, not with the Black Hood terrorizing the streets. Josie's dismissed the notion that she was acting out, claiming that she was simply living her life. Sierra reminded Josie of all the people in Riverdale with hate in their heart. The same people that used to write her awful letters. Since the Black Hood emerged, the letters had gotten worse. It was almost as if they were emboldened by the killer. Sierra informed Josie of the recent death threats. The things that were being said were terrifying, such as threatening to slit her throat or cut out her heart. Some of the residents of Riverdale were monsters. To make matters worse, the last letter she got, mentioned her daughter. Sheriff Keller then asked if Josie had received any suspicious letters or packages recently, which Josie replied that she hadn't. Sierra had worked so hard to get them where they were at, to shield them from such hate. She then joined Josie on the couch, and held her close.
Sierra comforted Josie the following night after learning that she had received a pig's heart as a gift, while at school. They suspected Chuck of being the culprit. Sheriff Keller had talked to him, and he promised he'd be leaving Josie alone. However, the Sheriff wasn't convinced that Chuck was responsible. After questioning him and checking his locker, they never found any evidence. Sierra instructed Tom to keep looking because if Josie said that it was Chuck, then it was him.
In the late hours of the night, Sierra ran into Josie's room as she had woken up in a panic, gasping for air and holding her throat.
Sierra is a beautiful middle-age woman with a slim figure. She has dark skin, brown hair and deep brown eyes. She often wears a lot of make up; lipstick, eye shadow, etc. As for her clothing choices, Sierra typically has on long, dark colored dresses.
Sierra is a proud and confident woman of color, often encouraging her daughter, Josie, to embrace the same qualities within herself. Having been elected as Mayor in such a small-minded and secluded town, Sierra was subject to hate, which presumably took a lot of heart and bravery to withstand. More than just a Mayor, Sierra is also a caring mother, being there for Josie in her time of hurt and motivating her to achieve her dream of becoming a famous singer.
