Okay, here's a summary of the article, presented as a friendly chat between Japanese and American friends in Japan, using speech bubbles and a casual, intermediate English level:

**(Scene: Two friends, Hana (Japanese) and Liam (American), are chatting over coffee.)**

**Liam:** Hey Hana! Did you hear about that really sad shooting at Brown University? It was all over the news.

**Hana:** Oh my gosh, yes! It was so scary. Two people died, right? And so many injured.

**Liam:** Exactly! They thought they caught the person who did it. Remember seeing all the articles online?

**Hana:** I do! They said they arrested someone on Saturday. I thought the case was closed.

**Liam:** Yeah, I thought so too! But… things got really weird. The mayor said they're releasing the person they arrested.

**Hana:** Seriously? Why? What happened?

**Liam:** Well, the Attorney General said they had some clues pointing to this person. But now, they think the evidence shows it’s someone else.

**Hana:** That’s so confusing! It's like a mystery!

**Liam:** Totally! And even worse, someone leaked the name of the person they arrested to the news. The Attorney General said it was a real shame that happened.

**Hana:** Oh no! That’s not fair to that person. Imagine being in that situation.

**Liam:** Right? It’s tough. President Trump even tweeted something about a suspect being in custody, but he had to correct himself later!

**Hana:** Wow. Things move so fast.

**Liam:** They're working with the FBI now, and they’re asking people to share any videos or information they might have. Hopefully, they’re going to find who actually did it.

**Hana:** I hope so too. It’s really terrible.



**Essentially, the summary covers:**

* The shooting at Brown University (deaths and injuries)
* The initial arrest and subsequent release of a suspect
* The reason for the release (new evidence)
