Generally speaking, criminal investigations are confidential except to the extent that law enforcement chooses to make certain things public. So, to answer your question, yes a detective can make information public about an informant.
However, had your boyfriend had an attorney with him at the time of his questioning, his attorney may have been able to negotiate an agreement with law enforcement to make him a confidential informant and keep his name out of the public/ out of the police reports. I have been able to negotiate such deals on several occasions for clients to keep their names confidential in both public press releases and in police reports.
Another consideration that may be even more important is that, even though he has cooperated with the police, he may still be running the risk of being an accomplice - which is charged the same as though he committed the crime. (See http://codes.ohio.gov/orc/2923.03). In order to assess the case, I need more information that you have provided - for instance, in order to determine whether he could be charged as an accomplice, I - or any attorney - would need to see your boyfriend's statement.
In some instances, burglary can be charged as a second degree felony and, therefore, carry a maximum of eight years in prison. (See http://codes.ohio.gov/orc/2911.12) In the meantime, he may not want to speak with law enforcement anymore without an attorney present.
I hope this helps.
All the Best,
Adam
