Reports of an alleged credit card scheme led police to Dyleski in the first place. The friend and Dyleski's mother knew about the alleged credit fraud days before the boy's arrest, the friend said.

According to interviews and court documents, the boy is alleged to have purchased marijuana-growing equipment using stolen credit card information.

A few days before Vitale's slaying, the friend said it became apparent Dyleski was involved in the credit scheme. The friend said he was able to trace Dyleski's orders of pot-growing equipment to a computer in Dyleski's home using credit reports furnished by neighbors.

According to court documents, one of Vitale's neighbors called police two days after her death and reported unauthorized use of his credit cards. The charges were traced to a hydroponic supply store and apparently were made in Fielding's name, sources have said.

The Sunday after Vitale's slaying, the friend and Fielding confronted Dyleski about the credit card purchases. While it is unclear whether Dyleski admitted it, Fielding called in an attorney to help, the friend said.

Dyleski was not there, but the law enforcement officers stormed in and pushed occupants to the ground, holding them there while they searched the boy's room, the friend said.
