They call themselves retired grandma Nancy Drews. One is a former emergency room nurse, the other a longtime elementary school teacher.

They make notes on coffee filters instead of index cards and wear clam diggers and sensible sneakers.

But thanks in part to the amateur sleuth work of Gemma Hoskins and Abbie Schaub, the 47-year-old unsolved murder of a young Catholic nun is gaining national attention. Earlier this year, the Baltimore County Police Department conducted DNA tests on the exhumed body of a priest in relation to the case. And now, with the debut of Netflix’s The Keepers, the seven-part docuseries in which the two are central figures, Hoskins and Schaub are being treated like Cagney & Lacey.

Netflix photos The Keepers looks at the 1969 murder of a Baltimore nun, Catherine Cesnik.

The two were classmates at Archbishop Keough High School in the 1960s, where Sister Cathy Cesnik was their teacher. But the nun disappeared suddenly on Nov. 7, 1969, after driving to a local shopping centre to buy some Muhly’s dinner rolls, cash a paycheque and purchase an engagement gift for her sister. She never returned home and her car was found directly across the street from where she lived, parked haphazardly, the rear jutting out into the road. The tires were caked with mud, and a twig hung from the steering wheel. The Muhly’s bag was still inside the vehicle.

Cesnik’s body wasn’t discovered until Jan. 3, 1970, abandoned in a snowy, wooded area just a few miles from where she lived.

Her death remained a sad, murky mystery until Hoskins got a call from a former Baltimore Sun reporter searching for anyone who had been a student of Cesnik’s.

Hoskins, wanting to help the reporter figure out who had hurt Cesnik, posted a message to a Facebook page for Keough High alumni but was berated for muddying up a space usually filled with birth and anniversary announcements with such an unpleasant topic. One person, however, came to Hoskins’ defence: Schaub.

It wasn’t long before the two started a new Facebook group, this one seeking justice for Cesnik.

Hoskins has always liked true-crime stories; she’s watched Dateline and 20/20 every Friday night for years. But it wasn’t until this mystery turned up in her own backyard that she realized just how adept she was at detective work.

Following tips often submitted through the Facebook page, Hoskins and Schaub began seriously investigating Cesnik’s death, which led to the theory explored in The Keepers that the teacher was killed after students confided in her about sexual abuse taking place at Keough. Numerous subjects interviewed by Hoskins and Schaub say they were molested by Father Joseph Maskell, who served as the school’s chaplain, counsellor and religion teacher.

The two made a good team: Schaub had a knack for research and, through Google, she learned how to access public records, digging up old court documents, sifting through microfilm and even filing Freedom of Information Act requests.

Hoskins, meanwhile, preferred to do the face-to-face work. If a new Maskell survivor popped up, she’d conduct the interview. She wasn’t afraid of knocking on doors or flirting to get information.

“Gemma and I are opposite souls,” explains Schaub, 65. “She is outgoing, confident and knows everybody in the community. I am far more of an introvert. I am keen to find substantive, hard facts. I want to see a paper trail. I don’t really like cold-calling people. So her strengths are my weaknesses.”

As a teenager, Hoskins had been terrified of the nuns who taught at her all-girls private school. They were old and serious, the white headdresses framing their faces so tightly it looked painful. There was a rumour that one of them didn’t have any toes.

But Cesnik was different. She was in her 20s, pretty and charismatic.

When Hoskins found out about the murder, she felt sick.

“The idea of her laying there for two months just makes me want to scream,” she says, “because she was so special. I can’t imagine her beautiful body and face — her presence — laying in the snow. It wasn’t right.”

Today, a small metal placard has been drilled onto an ivy-covered tree near where Cesnik’s body was found. It would be hard to find the memorial if you weren’t with someone who had been there before. The tree is on private land, hidden about 45 metres off the street in some woods thick with underbrush.

“Back when Cathy was found, this was just a place where people dumped their garbage. All these trees weren’t here,” says White, pointing through the greenery.

Hoskins feels confident that she and Schaub have made a dent in the cold case. Recently, she says, Baltimore County Police Officer Robin Teal asked to meet with them to hear about what kind of information they’d gathered. (Teal did not respond to a request for comment.)

“She told us, ‘You have done my homework for me,’ ” says Hoskins. “As we were leaving, she said we’d given her some really good smoking guns. She calls me probably once a week. But we just hope it isn’t a PR thing because of the documentary.”

Recently Hoskins, after 64 years of living in Baltimore County — and seeing Schaub several times a week — decided to move permanently to her beachside apartment in Ocean City.

It makes for a good place to study. She recently decided to pursue a criminal justice degree through a local community college. She can take courses online from her rocker and just finished criminology this spring. When she graduates, she’d like to start working for a private investigator.

She shouldn’t have trouble getting work.

The Keepers has garnered strong reviews from critics and Hoskins thinks the series could have a bigger effect than recent crime stories like Making a Murderer, The Jinx and Serial.

“I think that with Cathy dying so young, she could have had such an impact on our lives — but she’s having a bigger one now. And maybe that was the way it was supposed to be… Cathy — I think she’s driving the bus,” she says, her eyes watering. “My teeth are in this thing. I love that woman and (Maskell) was a monster and I’m going to see what I can do about it. I feel like this is what I’m here for.”

Downtown Keg closes… to reopen nearby

Free Press staff 2 minute read Friday, Jul. 31, 2026

Downtown Winnipeg is without a Keg restaurant — for a couple of months, anyways.

The Keg Steakhouse and Bar vacated 115 Garry St. on Wednesday, after more than five decades at the location. It will open in a new Donald Street apartment tower this fall.

Its move comes after years of waiting. The DSM, at 185 Donald St., sat as a partially started apartment block after its developer stopped operating and sought creditor protection in April 2023. The developer began the project in 2019.

Carrington Real Estate took over in 2024. Part of the 14-storey site’s initial plans — pre-Carrington — was for the Keg to occupy the main floor.

Book gives patients tools for navigating the Canadian health-care system and getting treatment they need

Janine LeGal 8 minute read 6:00 AM CDT

More than a few of us have been known to complain about the Canadian health-care system: the lack of staffing, the long ER waits, the challenge of finding a family physician, the lengthy waiting lists for specialized tests and surgeries. There’s been an outcry for answers for a long time.

The publication of The Canadian Health Care Guerrilla Handbook: How to Fight for What You Need is welcome news for anyone seeking those answers.

Written by Michael Decter, who served as cabinet secretary in Manitoba before his move to Ontario — and Mike McCarthy, patient advocate and consultant who brings a personal story of living with hemophilia, the book is a must-have, packed with answers to commonly asked questions that will help the reader navigate a complex and fractured system.

The book, written in plain language, talks about how to get what you want and need: a family doctor, diagnostic tests, appropriate medications, a second opinion, long-term care, home care, mental-health care — all of that and more is easily accessible in its 217 pages.

Hydro CEO needs to reckon with winds of change

Dan Lett 5 minute read Yesterday at 3:28 PM CDT

Methinks Hydro CEO Allan Danroth protests too much.

At a recent hearing in front of the Public Utilities Board, Danroth suggested Hydro’s plan to build a $3-billion natural-gas-powered generating plant near Brandon was being subjected to unfair criticism. The gas turbines are meant to bolster Hydro’s grid in the event that drought lowers output from hydro-generating stations.

After hearing submissions from interveners concerned about the gas-turbine plan, Danroth lashed out at the “constant, uninformed criticism” that has not only shaken trust in Hydro but also triggered threatening responses from the public.

Danroth said Hydro is monitoring “eight credible threats” against employees, five of which targeted the CEO himself. Although Danroth cited some specific incidents — employees being threatened with guns, and one where a homeowner set his dogs on a meter reader — he refused to elaborate on the circumstances.

240 WestJet flight attendants picket in Winnipeg

Malak Abas 6 minute read Sunday, Aug. 2, 2026

Winnipeg’s WestJet flight attendants took to the picket line outside of Richardson International Airport on the first day of nationwide strikes Sunday, while inside, frustrated flyers scrambled to re-route cancelled long-weekend flights.

The Canadian Union of Public Employees’ Ontario arm and the airline announced the strike would commence after the strike deadline was passed without a deal early Sunday morning. WestJet attendants have been without a contract since Dec. 31, 2025.

Hours later, the 240 WestJet flight attendants based in Winnipeg had walked off the job and were marching outside of the airport terminal, some carrying signs with slogans including “Tired with WestJet? So are We!” and “Unpaid Work Won’t Fly.”

Key issues causing the stalemate are wages and pay for work on the ground: the union says flight attendants are not being paid for some of that work, while the company says they pay for the work through a “credit hour” system rather than an hourly rate.

18-year-old woman shot by Winnipeg police officer

1 minute read Updated: Yesterday at 12:28 PM CDT

A police officer shot and injured an 18-year-old woman early Monday morning while investigating a College Avenue shooting.

A north district unit officer was in the area of Aikins Street and College Avenue at 2:27 a.m. Aug. 3 when he heard multiple gunshots nearby, the Winnipeg Police Service stated in a news release Monday.

The officer went to investigate and "was confronted by a woman and a 16-year-old youth." The officer discharged his gun and the young woman was injured, the police service stated. The woman was taken to hospital in unstable condition and was later upgraded to stable.

Police recovered a gun from the suspects and investigators later linked the 18-year-old woman and 16-year-old male to a shooting that occurred outside of a home in the 300 block of College Avenue. The 16-year-old was arrested.
