"another case of missing 13-year-old girl was reported in Benin, where one Akpan was fingered by informants during investigation"

Poster, I'm lost here, what do you mean by One Apkan was fingered by informants during investigation? Were you trying to say Apkan was identified by the informant during investigation? For your information: being fingered means "segxwal penetration of the person by/with finger".
