Barbara Lawlor, Nederland.  The Nederland Police Department and the Federal Bureau of Investigation have arrested the suspect who left an explosive device outside of the PD last Tuesday morning, Oct. 11. David Michael Ansberry, 64, was arrested on Saturday at Chicago's Midway International airport when he got off the plane.

The device was declared a legitimate explosive device that had failed to go off when the cell phone detonator didn't work. The Boulder Bomb Squad detonated the bomb at 1:30 Wednesday morning after advising residents of the procedure.

The United States District Court for Colorado has charged Ansberry, 64, with the offense of maliciously damaging or destroying or attempting to damage or destroy by means of explosive any property used in interstate or foreign commerce. The affidavit was written by FBI Special Agent Kevin P. Hoyland on Saturday, Oct. 15.

Agent Hoyland explains in the affidavit that he has not included each and every fact known to him concerning the investigation, just those necessary to establish probable cause.

A backpack found outside of the NPD, was brought inside of the police department by a detective thinking it was lost property. When he opened it, he found a cellular device with wires coming off the phone, connected to a battery and suspicious white powder. He carefully took the bag outside and then evacuated the shopping center.

When the Boulder County Sheriff's Office bomb squad arrived the device was removed and decommissioned by two robots, one of which removed pieces of the bomb. The cell phone was placed in a makeshift Faraday box to prevent a cellular signal from reaching it, and taken to the BCSO and forensically analyzed. The phone number assigned to the detonator had been dialed multiple times by another number in the attempt to detonate the bomb.

Both of the phone numbers were handled by a subsidiary of AT&T, TracFone and no subscriber information was available. Both phones were activated on Oct. 4. The selling company was listed as Blackhawk Network in Fountain CO.

Investigators  learned that Advantage Logistics used the same address which is a distribution company for Kroger brand grocery stores, including King Soopers. The stores where the phones were purchased were listed in Denver and in Longmont.

Surveillance videos show the purchases were made by a male, 3'6" with a pony tail a baseball hat and crutches. The transactions were made with cash.

A man with that description had been seen being evacuated from the Boulder Creek Lodge across from the shopping center and the motel confirmed that the man matching that description had stayed there for about two weeks. His address was listed as San Rafael, California. His T-Mobile account was cancelled on Thursday, Oct. 13.

A call records show that there were two outbound calls at 9 a.m. and 10:17 a.m. on Tuesday from the Verizon tower above Nederland.

Agent Hoyland says that these facts indicate probable cause of a Title 18, US Code, Section 844 violation.

The affidavit was submitted to Magistrate Judge Michael J. Watanabe on Saturday, Oct. 15.

The charges carry a sentence of five to 20 years, $250,000 or both. The affidavit indicates that the court will seek detention.
