The host of HBO’s “Autopsy,” Michael Baden is a forensic pathologist who investigates high-profile deaths and testified in cases like the O.J. Simpson murder trial.

His former landmarked Victorian-style townhouse, at 142 East End Ave., which he sold for $3.55 million in 2011, has traded hands again for $6.5 million. It was last asking $6.99 million.

The buyers are Sanjeev Bahl, president of Saitex, a Vietnam-based apparel company, and his wife, Aisha.

The 4,000-square-foot five-bedroom home features a skylight over the staircase, a full-floor master suite and a chef’s kitchen with wine storage and a dumbwaiter to serve the dining room above, according to the listing.

There are also four outdoor spaces, notes the listing, from a BBQ patio in the rear to a fifth-floor terrace and a wood-decked roof with an outdoor kitchenette overlooking Carl Schurz Park, Gracie Mansion and the East River.

Matthew Lesser and Ravi Kantha of Leslie J. Garfield repped this listing.
