From the first episode of _Death Note_ , a TV news reporter says

> 犯人は保育園内で死亡！

I can see that する is being omitted from this sentence. But I'm
curious/confused if other words or particles are also being omitted? In
particular,

> 保育園内で

is a bit confusing. Here 内 appears to be modifying 保育園 as if it were a
particle?

particles context
Understanding "犯人は保育園内で死亡！"
I thinks this 内 of 保育園内 emphasize the location of the event. It's no problem
保育園で gramally but maybe 犯人 is not a student of 保育園 in this case, so appending
内 is better expression.

answer
内 works as a suffix or as a standalone noun, similar to the English _inside_
(e.g., inside a car/the inside of a car).

When used as a suffix, 内 is read ない (always, I think). As hiroki's answer
suggests, it connotates the 'building'-ness of the preceding noun.

That is, 保育園[内]{ない}で sounds _in the building of the nursery_ while 保育園(の中)で
sounds broadly _in the nursery_.

Other examples of 内{ない}

  * 時間[内]{ない}: within the time limit
  * 期限[内]{ない}: before the expiration
  * 校[内]{ない}: inside school building

When used as a noun, 内 is read うち. For example, 内{うち}と外.

Also note that when talking about _inside X(location)_ , Xの内{うち} is not used.
It should be Xの中. (For non-location, 計算の内{うち}= _expected_ (lit. _within
calculation_ )).
