A former Iowa State student blamed for several computer burglaries on campus this summer and earlier this semester was arrested by the Department of Public Safety on Thursday night.

Marshall McCalley, 21, of Des Moines, turned himself over to DPS Lt. Angela Hart shortly after 11 p.m. at the Armory Building, according to DPS records.

Loras Jaeger, DPS director, said McCalley had been e-mailing Hart since Tuesday, and as a result of those communications eventually turned himself over to DPS.

Jaeger said he then was transported to the Story County Jail. McCalley was released early Friday on his own recognizance.

An arrest warrant for McCalley was issued last Monday after a DPS officer saw numerous pieces of computer equipment and audio/visual equipment with university identification tags in McCalley’s van.

Further investigation found that burglaries had taken place that night at the English Office building and at Carver Hall. McCalley’s van was found later that morning at about 5 a.m. and was taken into custody.

Search warrants were then obtained for the van, McCalley’s Des Moines apartment and McCalley’s parents’ residence in Boone.

Searches executed by DPS revealed more than $10,000 worth of stolen computer equipment in Des Moines and at least $3,000 worth in the van. Nothing was found at the Boone residence.

Although the arrest warrant for McCalley originally was for only two counts of burglary, Jerry Stewart, DPS associate director, said he is suspected in more thefts.

“We believe 12 area burglaries were solved as a result of this investigation,” he said.

Not all of the campus computer robberies have been solved yet, however. Stewart said several other cases still remain open from the computer burglary spree this summer.

No additional arrest warrants have been issued for any of the other cases or for suspects who may have been involved with McCalley.

Jaeger said the majority of the burglaries are believed to be of ISU buildings, but equipment was also found in McCalley’s apartment that may have been taken from the Boone Community School District.

Because of the wide geographic range of burglaries possibly committed by McCalley, Stewart said it will be difficult to decide exactly how to charge McCalley.

“We’re going to have to consult with the Story County Attorney’s office to see how the additional charges will be processed, given that more than one county is involved,” he said.
