A Park Police horse-mounted patrol officer stopped a blue Nissan pickup truck as it was leaving a lot in the Carderock Park unit in Montgomery County on the afternoon of April 5th. The officer immediately recognized the pickup and its occupant as being sought by the Park Police in several thefts from autos and subsequent fraudulent purchases with stolen credit cards. The driver gave false information to the officer and was taken to District 4 Station (Greenbelt Park) for further investigation. He was positively identified through fingerprint analysis at the FBI, at which time he waived his Miranda rights and was questioned. During questioning, he admitted that several warrants for his arrest for various credit card cases were outstanding in the state of Maryland. He was remanded to the Prince George County Sheriff's Office, which had seven outstanding arrest warrants against him. There are also four outstanding warrants against him in Howard County. USPP criminal investigation branch officers had previously obtained one of the Prince George County arrest warrants that had been filed against him. That warrant stemmed from the investigation of a theft from an auto at Carderock Park. Investigators have also linked Baker to other thefts in that park and other NPS units in the area. Warrants are being sought for those incidents.
