The charge for Susan Berman's murder has brought the mysteries surrounding Robert Durst back into the spotlight. Investigators may now be looking at Durst in the disappearance of two teenage girls in California in the mid 90s, reports CBS News correspondent Vladimir Duthiers.

Police cars were seen at Durst's Houston apartment Tuesday and witnesses said officers carried out two cardboard boxes.

Saturday, a day before the finale of the HBO documentary series "The Jinx," authorities arrested Durst in New Orleans. At the episode's conclusion, Durst's voice was revealed to have been recorded off camera, allegedly muttering to himself.

"What the hell did I do? ... Killed them all, of course," he said.

Monday, he was charged in the shooting death of his friend, Berman, in California in 2000. Outside a New Orleans courthouse Tuesday, Durst's attorney maintained his client's innocence.

"Bob Durst did not kill Susan Berman. He doesn't know who did," said Dick Deguerin.

Durst was never charged for the 1982 disappearance of his first wife Kathleen in New York. In 2003, he was acquitted of murder in the dismemberment of his elderly neighbor Morris Black.

Investigators have reportedly looked at Durst in the disappearances of two teenage girls in Northern California in 1997.

In June of that year, 18-year-old Kristen Modafferi disappeared after leaving her job in San Francisco. Investigators placed Durst in the Bay Area around that time.

Five months later, 16-year-old Karen Marie Mitchell vanished after leaving her aunt's store in Eureka, California. Durst allegedly visited that store multiple times while dressed in drag. A police sketch of a suspect appears similar to Durst.

Author Matt Birkbeck, who has reported extensively on Durst, insisted there's a connection.

"Before these cases even came up before the public, he had been living this random bizarre lifestyle," Birkbeck said. "Durst had visited with or seen Mitchell at a homeless shelter that she had volunteered at."

California law enforcement has not yet responded to "CBS This Morning's" request for comment on the two missing girls.

Durst could face the death penalty in California if convicted for the murder of Berman.
