On Friday, January 17, 1975, Hazel Mason didn’t show up for her shift in the cafeteria at Milford Memorial Hospital. She’d worked there 17 years.

That was so unlike her that the hospital sent a coworker, John Burton, to her house. He knocked, nobody answered, and her car was in the garage. Another coworker, Rae Marshall, called police for a welfare check.

Around 12:20 pm, officers forced their way into her house at 1003 Northeast Front Street. They found Hazel on the living room floor.

Rae Marshall was there and said it looked like Hazel had been sewing when she was attacked. The medical examiner said she was strangled.

There was NO sign of a burglary and no evidence of sexual assault.

She was last seen around 7 pm Thursday. Police put the time of death between 8pm Thursday and 9 am Friday.

Hazel Bernice Pleasanton Mason was 48. She lived alone, was married but separated, and didn’t have children. Coworkers said she went to church and was generous. Her supervisor said she never bothered anyone.

She left behind her mother, Sarah Pleasanton of Camden, a sister, and a brother. Her mother lived to 91 and died in 2000, 25 years after Hazel was killed, never knowing who did it.

No one has ever been arrested or publicly named as a suspect.

Hazel’s case is still open with Milford Police as case 51-75-0247.

If you know anything, you can send a tip through the department’s website or call 1-800-TIP-3333.

My question: Who was her husband?

I'm watching "Unmasking the Tylenol Killer" right now, and they're showing the note "Toomey" left with the instructions. I've noticed that they show the last line that was blacked out in the original segment, and it says "Yes there is a record of this communication."

Does anyone have any idea why that would've been blacked out? It also looks like it was partially erased or something, as the letters are smudged.

I wonder if "Toomey" blacked it out, and then law enforcement used alcohol or something to remove the ink to read what it said. It does look like there was ink that ran on the page they show in the doc.

Nolan Wells’ death has already gone before a grand jury without resulting in criminal charges. His family says the case still contains unanswered questions that warrant another look.

William Morton was arraigned and charged with one count of murder on Tuesday, Oct. 6. His DNA matched the biological fluids on the inside of the victim Hillary Hellewell's pants.

Investigators know who the little boy found inside a suitcase was and eventually tracked down his mother. What remains disputed is how he died — and whether the evidence actually proves he was murdered.

Lisa Mott was 12 years old when she disappeared from Collie, Western Australia, on October 30, 1980.

She had spent the evening playing basketball with friends and later stopped at a nearby pizza shop. At around 9 p.m., Lisa began walking home. Witnesses last saw her crossing a railway line toward Forrest Street before getting into a yellow panel van. She was never seen again.

More than four decades later, police are still trying to determine who owned or drove that van. In 2025, investigators searched bushland near Collie after renewed attention turned to a yellow Holden panel van that had been found abandoned there years earlier. Police later said they had received more than 190 new reports from the public, but the case remained unsolved.

A $1 million reward remains available for information leading to an arrest and conviction in Lisa’s case.

After more than 45 years, do you think identifying the yellow panel van could still be the key to solving Lisa’s disappearance?

In 2017, 25-year-old Emily Dull Anderson disappeared in Loves Park, Illinois.

Emily was last seen in the early morning hours of June 19 after spending the evening at several local establishments. Her family reported her missing after she failed to return home.

111 days later, Emily’s vehicle was recovered from the Rock River with her body inside.
Years later, her family is still searching for answers.

Emily’s sister, Caitlin Dull, has continued advocating for her sister and keeping her case in the public eye. The family believes someone may have information that could help explain what happened during the early morning hours of June 19, 2017.

If you have information about Emily’s disappearance or her whereabouts that morning, contact the Loves Park Police Department at 815-654-5015.

Please consider sharing Emily’s story. Someone may recognize a detail, remember a conversation, or know something that could help bring answers to her family.

Edit - I’m not sure if there’s anything deeper here or not. Her sister strongly believes someone else is involved and her case is still marked unsolved so I thought I’d help spread the word. Thanks for taking a look 🤍

Franklin Police Chief Kirby Cochran announced an indictment was returned against Michael Jerome James for two counts of murder in the deaths of Blake and Chynna Dickus on July 24, 2006. James, now 35, would have been a teenager when the murder was committed.

I’ve looked back to see if there have been any updates on 10 year old Amy Mihaljevic’s 1989 unsolved murder. I will link a recent article that quotes her dad, who is turning 80 soon & wants to finally know what happened to his daughter before he dies.

For those unfamiliar, Amy left her school and walked to where she was abducted from, the Bay Square Shopping Center. in the Cleveland suburb of Bay Village, Ohio on October 27, 1989. Amy’s remains were found months later, 02/08/1990, in a field fairly close to county road 1181, Ruggles Township in a rural area of Ashland County, OH. An autopsy would reveal that Amy died of sharp force injuries (multiple stab wounds.)

If you read a lot of true crime, you likely know Amy’s case by its sad circumstances: a man had called & spoken with Amy posing as a coworker of her mom’s, telling her Amy’s mom had gotten promoted and offering to take her to buy a gift for Amy’s mother to celebrate. While the caller told Amy to keep all this a secret, this is known because she told her brother and a friend.

I’m frankly not here to do a synopsis of the case—really, I wanted to share a gofundme by the Mihaljevic family (verified) to raise the funds for modern advanced DNA testing to try and find answers before her dad passes away. I’d share a video posted on Father’s Day of Mark Mihaljevic, a clearly elderly man, speaking about her, but it’s against sub rules: google will get you there though.

Every penny goes to the Bay Village Police Department’s Amy Fund—these are extraordinarily advanced tests than the norm & most cost over 6K each, so the family is trying to make sure LE have every financial resource necessary to get this case finally solved sooner than later.

I have no affiliation with any of them, I’ve just seen so many “lesser” gofundme’s quickly generate so much $ and it breaks my heart to think that an 80 year old man living with 37 years of such heartbreak has to be the one trying to navigate the internet to advocate for her. It’s been up for months & yet it is only halfway to its goal. Please help if you can & SHARE AROUND
