Officers in about 10 patrol cars descended on a Super 8 Motel in Cromwell, Conn., Thursday morning, only a day after Clark, whom news outlets say was the only "person of interest" in the case, had been released after having DNA collected by police. Sources said the DNA definitively linked Clark to Le's murder and that Clark went quietly with police when they took him from the motel.
His bond set at $3 million, Clark is expected to be arraigned within 24 hours.
Le went missing Sept. 8, and her body was discovered Sunday, the day she was to have been married.
Clark was a lab technician who cleaned the cages for lab mice at the university, and reportedly knew Le because she used the mice in her experiments and worked in the same building where her body was found. He reportedly failed an FBI lie-detector test after her disappearance, and had what were described as defensive wounds on his chest.
On Wednesday, a coroner's report was released stating that Le was strangled to death and categorizing her demise as a homicide. Her body was discovered in a space in a basement that only someone familiar with the area would have known about, police said. The building had strict security measures that allowed access to only a handful of people.
