SNYDER, Texas -

Snyder police and the Texas Rangers continued Tuesday to try to find the 21-year-old girlfriend of a man found slain recently in his Snyder home.

“At this time the whereabouts of Cassandra Lopez is still unknown,” Snyder Police Chief Terry Luecke said Tuesday in an email.

Lopez has been identified as a “person of interest” in what has been labeled a homicide. Omar Alejandro Diaz was found dead at his Snyder residence on Saturday, March 22. He was last seen with Lopez on March 14 in Lorenzo, according to a recent state Department of Public Safety news release.

“The Snyder Police Department and the Texas Rangers are still following up on some information to try and locate her,” Luecke said. “I will send out updates when there is new information.”

In asking for the public’s help in locating Lopez, the DPS release said she has a tattoo of “Respect” on her upper chest. The tattoo reads “Loyalty” when looked at upside down.

Diaz’s red 2004 Pontiac Grand Am GT was found abandoned in “the Lubbock area,” Luecke said earlier this week.

While Luecke said Lopez is from an undisclosed “another part of the state,” Diaz is from the small town of Lorenzo, which is located northeast of Lubbock.

Snyder police say Diaz and Lopez had recently moved to Snyder in December from Lorenzo after Diaz had gotten a job at Price Daniel state prison unit.

Jerrod Pickering, superintendent of Lorenzo ISD, said he was high school principal when Diaz graduated from Lorenzo schools in 2011.

Diaz's death, Pickering said, ”came like a punch in the gut.”

Pickering said Diaz was a “good kid” who was “really getting his life in a good direction.”

Calling Diaz’s family “fantastic,” Pickering said Diaz wasn’t “a troublemaker or anything like that.”

Pickering said he wasn’t aware how Diaz met Lopez, but that she wasn’t from “around here.”

According to Pickering, Diaz has a sister who is attending Lubbock Christian University and another sister and brother who are in Lorenzo ISD schools.

While his parents do not speak English, Pickering said they have always been supportive of the schools and ensured their children were well-behaved.

Texas Rangers are asking those with information on the whereabouts of Lopez to contact them at (806) 637-3713 or the Snyder Police Department at (325) 573-2611.
