Second suspect arrested in 24-year-old Frank Weiss murder case

The Frank Weiss cold case just changed shape. Frisco police arrested 57-year-old Keith Hart of Waxahachie on a murder warrant at about 7:45 a.m. May 8, only two weeks after the earlier arrest of Weiss’ former wife, Lisa Honrud, in the 2002 killing of the Plano businessman.

That second arrest matters because it pushes the investigation beyond a simple suspect-and-victim story. With Hart now in custody, detectives appear to be testing a broader theory of the crime, one that could include planning, concealment, and lies told after Weiss vanished. Chief David Shilson said the new arrest moved the department closer to closure for the Weiss family, but the case is still active and the full sequence of events has not been laid out publicly.

Weiss was found dead near Lake Lewisville inside Frisco city limits, his body wrapped in black bags, tied with rope, and weighed down with 50-pound sandbags duct-taped to his legs. He had been shot twice in the chest with a .38-caliber gun. Those details have long made the case stand out as more than an ordinary disappearance. They point to deliberate concealment, not panic.

Investigators said the breakthrough came after Frisco reopened the case earlier this year with a six-officer team, re-interviewed witnesses, and began spotting inconsistencies that had never been resolved. Police also said the work depended on a key witness, modern technology, and advances in investigative techniques. That combination helped turn a dormant file into an active homicide case again, and then into two arrests in rapid succession.

An arrest affidavit says Frank and Lisa Weiss went to dinner on June 2, 2002, and that was the last time he was seen alive. His body was found two days later. The affidavit also says Weiss had recently asked for an annulment, which Honrud signed, and that he changed the beneficiary of his life insurance policy about a month before his death, naming his daughter as the sole beneficiary. Another reported detail says a witness gave Honrud a .38-caliber revolver before Weiss disappeared, and that Honrud later allegedly said the gun had been thrown off a bridge over Joe Pool Lake.

Carla Weiss has said she believes others were involved in her father’s death and wants everyone responsible brought to justice. Frisco police continue to ask for tips by phone, text, or through the department app, as the 24-year-old Dallas-area homicide moves from cold file to widening prosecution.
