An apostrophe means one of two things - either you're leaving out some letters (like can't means cannot or doesn't means does not) or you are indicating possession. If you put an apostrophe after the word suspects, you get suspects' which means "belonging to the suspects." An example sentence would be something along the lines of "The suspects' belongings are at the police desk."
