Frisco police say a 2002 killing moved forward after new witness information and modern investigative work.

FRISCO, Texas — Two Waxahachie residents have been arrested on murder warrants in the 2002 death of Plano resident Frank Weiss, whose body was found near Lake Lewisville after a case that stayed open for nearly 24 years.

Frisco police first arrested Lisa Honrud, 55, on April 20, then arrested Keith Hart, 57, on May 8. Honrud was married to Weiss at the time of his death, police said. Authorities have not released a full account of Hart’s alleged role, but they said the second arrest came after continued progress tied to time, cooperation and key witnesses.

The current case began with an old call number and a new warrant. Police said members of the Frisco Police Department worked with the Waxahachie Police Department to take Honrud into custody at about 7:47 a.m. April 20. Chief David Shilson said the arrest was “an important step toward justice” for the Weiss family. Less than three weeks later, police announced Hart’s arrest at about 7:45 a.m. May 8, again with help from Waxahachie police. Shilson said the second arrest moved investigators closer to closure for the family and the community. The police department has not said whether additional arrests are expected.

The homicide dates to June 2002, when Weiss was last known to have gone to dinner with Honrud, according to an arrest affidavit described in local reporting. Investigators wrote that the dinner took place June 2, 2002, and that it was the last time anyone saw Weiss alive. His body was found two days later near Lake Lewisville within Frisco city limits. The affidavit says the body was wrapped in black bags, tied with rope and weighed down with sandbags that had been duct taped to the legs. Investigators believe Weiss was shot with a .38 caliber firearm before he was placed in the lake.

The same affidavit says Weiss had sought an annulment before he was killed. Honrud signed and agreed to it, investigators wrote. Police also examined a life insurance change made about a month before the killing, when Weiss reportedly named his daughter, Carla Weiss, as the sole beneficiary. Authorities have not said whether Honrud knew about that change. The records place the marriage, the annulment request, the insurance filing and the final dinner in the period investigators now treat as central to the case. Police have not publicly released all evidence used to support the warrants.

One of the clearest allegations in the affidavit involves a firearm. A witness told detectives that the witness had given Honrud a .38 caliber revolver before Weiss disappeared. After learning Weiss had been killed with a .38, the witness confronted Honrud about the gun, according to the affidavit. The document says Honrud told the witness, “we got rid of it,” and said it had been thrown from a bridge over Joe Pool Lake. The alleged statement became part of the account investigators used after the case was reexamined decades later. Police have not said whether the gun has been recovered.

The case also includes an alleged explanation given to Weiss’ daughter after he vanished. According to the affidavit, Honrud told Carla Weiss by phone that her father had gone to Cancun and did not want to be bothered. Investigators now allege Weiss was already dead and had been left in the lake. Carla Weiss later described her father as a warm and present parent, recalling that he once carried her on his shoulders for hours so she could ride a pink Dumbo ride and that he worked as the DJ at her 16th birthday party. “He deserved better than this,” she said.

Frisco police have described the case as a cold case homicide advanced by new information from a key witness, modern technology and investigative techniques. The department has not identified the key witness in its public statements or detailed the technology involved. A police spokesperson said the city and department have grown since 2002, including in the talent and experience of investigators. That growth now frames a case that began when Frisco was much smaller and Lake Lewisville remained a familiar boundary between fast-growing suburbs and open shoreline.

The second arrest adds a new legal layer. Hart, like Honrud, was arrested on a murder warrant connected to Weiss’ death. Police have not publicly described the relationship between Hart and Honrud, the evidence against Hart or whether prosecutors allege a shared plan. They also have not said whether either defendant has entered a plea or retained counsel. In Texas, an arrest warrant marks the start of a criminal court process, not a finding of guilt. Prosecutors still must present evidence, and both defendants are presumed innocent unless convicted.

For the Weiss family, the case now stands in a different place than it did for most of the past two decades. Police say the original 2002 call remains tied to the 2026 warrants, and they have asked for any remaining information about the killing or related offenses. The next milestones are expected to come through court filings and any further police statements after the May 8 arrest.
