Amid Search of Home, a Theory Emerges in Nashville

Was it a suicide bombing? That's the theory emerging from the rubble in Nashville after the Christmas morning explosion, reports CNN. The outlet quotes two anonymous law enforcement sources, though authorities have not publicly speculated on the idea. However, it syncs with new developments. Coverage:

• 'Person of interest': He has been identified as a 63-year-old white man who lived in the Nashville suburb of Antioch, reports the New York Times. Authorities have not named him publicly, but outlets including CBS News and ABC News have done so. Click on either link for that detail.
• The RV: Federal agents scoured the suspect's duplex home in Antioch on Saturday and removed items. Neighbors say the man had an RV like the one that exploded Friday morning, and neither the man nor the van have been seen since the bombing. The AP reports that a Google Maps image confirms that an RV had been parked at the residence for some time prior to the blast.

• Fishy detail: ABC reports that the man transferred ownership of his home to a woman in Los Angeles for $0 last month, according to court documents. He was believed to have lived at the residence alone, and neighbors say he largely kept to himself.
• Remains: Federal authorities have confirmed that tissue found at the scene was human remains, notes the Tennessean, though they can't say for sure yet if they belonged to the suspect or to anyone killed in the blast.
• AT&T: Authorities are still unsure whether the fact that the RV was parked outside an AT&T facility has any significance. Meanwhile, service continues to be disrupted in Tennessee and elsewhere. AT&T has put up two temporary cell towers in downtown Nashville, reports NBC News.
