GREENWICH, N.Y. -- No one has been formally charged yet in the disappearance of 12-year-old Jaliek Rainwalker, but at a news conference on Monday, authorities said the boy's adoptive father, Stephen Kerr, is a "person of interest" in the case.
Jaliek was last seen on Nov. 1 with Kerr.
Police said there are not only inconsistencies with Kerr's story but that he has not been fully cooperative with authorities.
He has reportedly refused to take a polygraph test from the FBI and has also failed to answer a questionnaire from them.
Cambridge-Greenwich Police Chief George Bell said, "With a missing 12-year-old, it's his son, he should be more forthcoming. There should be no reason for him not to cooperate with the police at this point."
State Police Lieutenant Scott Coburn said, "He was the last one to see Jaliek. His wife has taken a polygraph. He has declined so, yes, he has set himself apart from everyone else."
For his part, Kerr has suggested that Jaliek may be involved in gang activity in the Albany area.
But police said with a $25,000 reward being offered, they believe gang members would have come forward by now to collect the cash if they knew where the boy was.
Anyone with information on the whereabouts of Jaliek Rainwalker is asked to contact the Cambridge-Greenwich Police Department.
