Does this type of grammatical construction give an ambiguous meaning?

A girl was found in a house belonging to one of two criminals; is it correct to express this in the following way:

The girl was found in one of the criminals' houses.

Does the plural use of 'house' suggest that the criminal in whose house she was found has more than one house? Or is it ambiguous meaning that he could have one or more houses?

Another example:

The drugs were found in one of the men's cars. ?

Does the meaning suggest, as in the other example above, that the man in whose car the drugs were found has more than 1 car? Or again, is it ambiguous suggesting that he may or may not have more than 1 car?

Solution 1:

Let us analyze this sentence:

The girl was found in one of the criminals' houses.

There is a group of criminals. At least one of the criminals owns at least 1 house, while the total number of the houses owned in the group is more than 1. Therefore, this group of criminals owns a certain number of houses, in one of which the girl was found.

It's like saying:

This product was created in one of the company's laboratories.

The same way there are many laboratories belonging to 1 entity, "the company", there are many houses belonging to 1 group of people, "the criminals."

Therefore, the sentence is perfectly correct and there isn't really any "more proper" way to express what it says.

Regarding the ambiguity, I wouldn't say it's ambiguous. It simply doesn't specify the number of houses per each person in the group it describes. Therefore it's impossible to determine what number of houses each person owns.

It may be like this:

Criminal 1 owns 3 houses.
Criminal 2 owns 1 house.
Criminal 3 owns 12 houses.

If in one of those houses a girl was found. It really isn't important which person owns how many, therefore the sentence isn't prepared to deal with it in the first place.

EDIT

Adding another example to back up my case:

I'm interested in buying one of the red houses on Lincoln Street.

Explanation example: There are 30 houses on Lincoln Street. 12 of them have the property of "being red." I want one of those!

I'm interested in buying one of the criminals' houses.

Explanation example: There are 1 000 000 houses in my town. 6 of them have the property of "belonging to a group of criminals responsible for robbing a bank." For some reason I want to buy one of those houses!

Solution 2:

The first could mean that there were several criminals, that they had several houses and that the girl was found in one of them. The second could mean that there were several men, that they had several cars and that the drugs were found in one of them.

Any writer wanting to make it quite clear that in the first there was one criminal with several houses would be well advised to write The girl was found in one of the houses of one of the criminals and any writer wanting to make it clear that in the second there was one man with several cars would be well advised to write The drugs were found in one of the cars of one the men. Fortunately, the need for either sentence is unlikely to arise very often.

Solution 3:

Yes, the sentence, "The girl was found in one of the criminals' houses" is ambiguous. It could mean:

(a) Each criminal owns one house, and the girl was found in the house owned by one of the criminals.

(b) The criminals collectivelly own several houses, that is, the criminals are part of some organization, and that organization owns several houses. The girl was found in one of these.

(c) One or more of the criminals owned several houses, and the girl was found in one of the houses owned by one of the criminals.

(d) It's even possible that it means: One of the criminals owns more than one house, and the girl was found in all of these houses. That doesn't make a lot of sense in this context -- how was she found in more than one house? But it would be quite plauble in a similarly-constructed sentence in a different context, like, "The drugs were found in one of the criminals' houses." That could mean drugs were found in each of his houses. (I suppose in the original sentence, the girl may have been murdered and pieces of her body found scattered among the houses.)

If the ambiguity is important, you can clarify by rewording the sentence. Like, "The girl was found in a house belonging to one of the criminals", versus, "The girl was found in one of the houses owned by the crime syndicate."
