Walter Kramer goes jogging along the same route every Friday. That means he must have also gone on the day he died. Take a close look at the route. What points does he pass along the way where you could also send Betty Barker?

2.
Mike Gordon and Frank Richards were the last to visit the profile. The third person is irrelevant. So they must have seen that Walter Kramer goes jogging on the same route every Friday.

1.
Walter's email address is in the classified ads: kramer_walter@dschimail.com. Go to www.dschimail.com

2. Security questions:

1) You can find out the color of his first car from the interview with Walter Kramer. It was red.

2) His wife is Sonya Kramer. Her birth year is listed in the newspaper: 1974. You will also hear her birthday indirectly in Walter's voicemail box: January 18.

3) You can get the answer from the printout of his social media profile: Wally

1.
You can get the password by listening to the audio of Mike Gordon in the client area of Jones & Donnell. Then check Walter Kramer's horoscope. The last word is "week," which means that is the password.

2. There are two documents in the cloud storage:

Chat backup: As you can see from the chat, Walter and his wife, Sonya, made up after Walter learned about the affair. They are also discussing their plans to escape to Brazil, which they are supposed to do on February 18. It is also clear from the chat backup where Walter was on the evening of February 13. He was at Eddy Barker's farm, and specifically in the barn (Betty Barker will find his wallet there when you send her to check it out). He was planning to test his own samples from Eddy's field to make sure there really wasn't any mercury in them.

My recording: You see a video taken at 1:50 p.m. on February 13, 2020, obviously secretly recorded by Walter. Have you already figured out where Walter was at that time? If not, take another look at the photo of the kitchen. The person who was secretly recorded is talking on the phone to someone else about a third person being "given stuff" and that person "regularly" going to the other person on the phone, saying that the following week is "the last time." You can identify Eddy Barker as this third person from his calendar. So his physician, Dr. Lee, was obviously slipping him something in his vitamin shots.

Betty finds Walter Kramer's wallet in the barn. He must have lost it there the day before his death. His ID is inside, but that's not all. A reminder card listing the number for his voicemail is also inside. Call the number listed there.

If you can't reach the voicemail box or don't want to call on the phone, you can also listen to the audio directly here:

AgriTec SE bought Walter Kramer's company. They would have tried anything (probably even criminal activity) to prevent publication, but that wasn't necessary. According to the emails in Walter Kramer's account, 15 million dollars changed hands.

Walter Kramer is the owner of HighFlower Inc. According to the transaction receipt, the overdraft limit of $150,000 has almost been reached. Walter could not have taken on any additional costs that would need to be paid at the start of each month.

The AgriTec debit is interesting, too. Why should Walter buy fertilizer from his competitor? For a clue, log in to the client area of Jones & Donnell (once you have the password).

You can learn from his email account how Walter got out of debt.

Sonya Kramer and Sergio Beneventi spent a weekend together at a fancy hotel. They seem to be having an affair. If they're found out, Sonya's prenup says she won't get a penny if she and Walter divorce.

The photo (the one Betty sends you) shows the same pouch of sand that was inside the envelope. That proves that the sand came from Eddy's field.

Betty writes:
So I looked around in the barn. Nothing but old stalls for the cows we used to have. There's a mask hanging from the fuse box, and some straw scattered around next to it. But then I did find something really interesting. Walter must have been here again at some point shortly before his death. His wallet is on the floor of the barn! There are also a bunch of weird test strips lying on the table. They're all the same color. Strange. Nobody has been here since the accident and my husband's arrest, so no one had a chance to find this stuff. I'm glad you sent me to double check! https://media.hidden.games/HiddenGamesTatort/uploads/F3_us_Portemonaie_US_NEU_Klein.jpg

Oh, Walter has the same phone provider as us. You can check his voicemails online at https://tele-comi.com

Look very closely at the photo. You might need to enlarge it. You'll see something lying in the grass. It's the fraternity ring from the newspaper. So someone must have lost it there.
