WESLACO, Texas (AP) — DNA evidence taken from a double-murder in South Texas 23 years ago has led police to a man they believe may be responsible for the unsolved crime.

Weslaco police spokesman J.P. Rodriguez said Evan and Wilda Squire were gunned down in their trailer home Nov. 13, 1988.

The sleeping elderly Canadian couple awoke to find several intruders in their home. The Squires were shot multiple times before their assailants fled.

DNA evidence taken from the crime scene was entered into a law enforcement database.

More than two decades later, the DNA of a 41-year-old man in police custody in Grand Rapids, Mich., matched.

The Monitor of McAllen reports Thursday that police declined to release the man’s name but said he faces extradition to Weslaco on capital murder charges.
