Mrs. Cunningham – The Museum Curator

Q: What time did you arrive at the museum on Thursday, June 23rd?:

A: I arrived at 7:30 a.m. like I do every morning. I am always the first one to open the museum doors. Early bird gets the worm, I always say.

Q: As a curator, your job is to oversee the artwork. When did you realize the painting was missing?

A: Every morning I do my rounds of checking the artwork. The Mona Lisa is one of the first pieces I check. I would say it was about 9:00 a.m. when I realized that it was gone. I was the one who alerted the authorities.

Q: According to you, who was the next person to arrive at the museum?

A: The next person that I saw come into the museum was Mr. Jones, the museum’s art maintenance man.


Mr. Jones – The Museum’s Art Maintenance Man

Q: What time did you arrive at the museum on Thursday, June 23rd?

A: I arrived at the museum at about 6:30 a.m. I am always the first one at the museum. Mrs. Cunningham doesn’t know that I am there before she is. She’s kind of out of it if you ask me.

Q: That’s odd, because Mrs. Cunningham stated that she was the first to arrive at the museum. Which door did you come through when you entered the building?

A: There are two entrances to the building. On the map below, you can see the employee entrance and the main doors. I always come through the employee entrance. Mrs. Cunningham always comes through the main doors.

Q: So you know Mrs. Cunningham and Mr. Jones quite well?

A: Yes, I’d say so.

Q: Is there anything else you’d like to add?

A: I’d just like to say that I had nothing to do with this awful tragedy. The Mona Lisa was my favorite painting in The Louvre and I would never do anything to harm her! I just hope she is found in one piece!

James Briar – Gift Shop Attendant

Q: What time did you arrive at the museum on Thursday, June 23rd?:

A: I think it was about 10 a.m., somewhere around there. When I showed up, there were a lot of cops outside. It was weird.

Q: Have you ever felt suspicious of one of the other museum employees?

A: Well, Nancy Smith would stand in front of the Mona Lisa for hours. I think she was obsessed with that painting. Kind of strange if you ask me.

Q: The night before the robbery, did you notice anything suspicious?

A: Hmm…now that I think about it, yes. There was a piece of tape around the lock of the employee door. I didn’t remove it. I thought it was there for a reason.


Amelia Johnson – Late Shift Museum Tour Guide

Q: The night before the robbery, what time did you leave the museum?

A: Well we close at about 10 p.m., so I would say that I left around 10:30 that night.

Q: Did you notice any suspicious activity that night?

A: I did see Mrs. Cunningham walking around the parking lot when I left. I thought that was a little strange. But that crazy old woman is always here. If I didn’t know better, I’d think she even lives here.

Q: Anything else we should know?

A: Watch out for Mr. Jones. That’s all I’m going to say.



Amelia Johnson was the last person to leave the museum the night before the robbery happened.

Mrs. Cunningham had been seen walking around the parking lot late the night before the robbery.

Mr. Jones and Mrs. Cunningham were not fond of each other.

James Briar was an irresponsible teenager.

Nancy Smith loved the Mona Lisa. She would spend her lunch break admiring the painting.

John Friedberg was very fond of Mrs. Cunningham. He would do almost anything for her. He tried to keep it a secret, but many people knew.

John Friedberg usually left the museum around 5 p.m. The night of the 22nd he left around 10:30 p.m. He said he was working on a special project for the museum’s event the next week.

Mr. Jones was the only museum employee who had access to the Mona Lisa’s safe combination. Mr. Jones kept a copy of all the museum’s safe combinations in a locked filing cabinet in his office.

Mr. Jones realized that the keys to his filing cabinet were missing and the safe combinations had been stolen.

Amelia Johnson was the last employee to leave on June 22nd .

Mrs. Cunningham was a persuasive and credible person. She was well liked by most of the staff and they trusted her.

Mrs. Cunningham had made a comment to Nancy Smith, saying, “I would love to hang that beautiful piece of artwork in my home. The Mona Lisa is just magnificent!”

Mr. Jones had told Mrs. Cunningham that he did not give the promotion to Amelia Johnson, because she was an undependable employee.

John Friedberg was a mastermind at eavesdropping.

Mrs. Cunningham did not feel the same way about John the way he felt about her. She thought he was a little odd.

James Briar said that he saw John Friedberg in Mr. Jones office.

Fingerprints from the crime scene show that Nancy Smith had touched the Mona Lisa’s safe combination.

Mrs. Cunningham often walked around the parking lot of The Louvre late at night for exercise. Her apartment was only 3 miles away. She was very dedicated to her job.

Mr. Jones failed to report that his safe combination files had gone missing. The police thought this was suspicious.

Mr. Jones had a roll of duct tape in his office.

  1. I think Nancy Smith stolen the picture beacause
    There was a piece of tape around the lock of the employee doorand Nancy Smith use the employee entrance she arrived at 9:00 o’clock and mrs Cunningham at 9:00 o’clock realised that the painting of Mona Lisa is missing.She also love Mona Lisa .And fingerprints from the crime scene show that Nancy Smith had touched the Mona Lisa’s safe combination!!!

  2. I think Nancy Smith stoles the painting of Mona Lisa because: she likes this painting , she arrived at the Louvre at 9:00 o clock and Mrs Cunningham at 9:00 o clock she realized that the painting of Mona Lisa is missing.

  3. I think that Mrs Cunnighan has stolen the Mona Lisa painting. And she even tried to make Mr Jones look guilty by using the tape.

  4. Nancy Smith because he love the Mona Liza painting

  5. I think 5hat Mr Jones called Nancy to his office to tell her that he is promoting her and she touched the combination of the Mona Liza that was upside down to his table with the others because he wanted to rearrange them. But when Nancy got away John went there to hear that the combinations are in the cabine. But there was James too who saw him there. So the night he stayed too late for that «project» in reality he was there to steal Mona Liza. I also think that he asked Mr Jones to take the key to his room to take some things for the project. Jones without knowing that he knew about the files he borrowed him the key. Then John went to the room found the keys for the cabin and took the file of Mona Liza. But when he was still there,before John goes there, James saw the tape around the door. It was there because John didn’t wanted anyone to get there before him. (that’s not the best explanation about this but anyway)
    The next day Mr. Jones saw that the combinations were gone but he didn’t record because he might didn’t have something to record or realized that his phone was off battery. And John didn’t talk to the authorities because he was afraid that they will find him.
    Now you may ask «OK but why he did that?» Well the answer is simple. Because as he himself said he was very close to Mrs. Cunnighan. He would do anything for her. That was also a reason that she thought he was odd. And because he somehow learned about what she commented to Nancy, even if she didn’t actually meant it as I believe, he wanted to make this dream come true. To have this piece of art to her home! Now that I mention her, I believe that because she was so good she wouldn’t do something bad. So she really did that day taka a walk for exercise and in this specific place because it is a good place. Amelia didn’t seem to have to do with all of this as well as James who just saw things. And Nancy, yes she was too obsessed the painting but as she herself stated, she couldn’t do anything to harm her. And Jones had the files for a reason it doesn’t make sense to my mind that he is the robber.
    Well that’s just my theory! I think it makes sense!
