Still an apparent mystery is where the guardrail came from.
Greene said the guardrail was not MTA equipment. Dave Buck, a spokesman for the State Highway Administration, said the agency knows of no missing guardrail from the roads it maintains in the area. Dave Fidler, a spokesman for the Baltimore County Public Works, said officials there were not aware of any missing guardrail. Both Buck and Fidler said theft of guardrail has not been a problem recently.
Someone who places a heavy object on a transit line could face a variety of state criminal charges, with their severity depending on whether a train had been damaged or people had been hurt or killed.
Even if no damage is done, interference with a railroad by placing something on the tracks with intent to obstruct or derail a train is a felony punishable by 10 years in prison and a $5,000 fine.
The investigation of the guardrail incident, as well as that of the deaths of the two Lutherville teens, is now in the hands of the Baltimore County Police Department, which took over the case from the MTA Police at the request of the transit agency.
County police spokesman Bill Toohey said homicide detectives looking into the case would appreciate any information the public could provide about missing guardrail in the area or who might have placed it on the tracks. He urged anyone with information to call 410-307-2020.
Toohey said that so far police have no idea who put the guardrail on the track.
"There seems to be no indications the boys did it," he said.
