(McKinney, Texas) – David Wayne Cahill, 52, of Oklahoma received 24 years in prison on Thursday for Aggravated Robbery, announced Collin County District Attorney Greg Willis.
Jury trial testimony revealed that on the evening of September 1, 2011, Cahill robbed a 79 year old man in the man’s home. Cahill first attacked the victim on the victim’s porch and then pushed the man into the house. Cahill then stole the elderly man’s wallet as he pinned him down. Cahill then released the elderly victim, and ran to his still-running car for a quick getaway. The 79 year old victim was terrified and because of a heart condition, had difficulty breathing.
Plano police took the report of the robbery. Initially they had no named suspects on the case. But two weeks later, a detective from Oklahoma contacted a Plano detective. Cahill had been arrested for the Oklahoma robbery of an 85 year old man, and the Plano victim’s wallet was found in Cahill’s trunk. Plano Det. Brian Pfhanning interviewed Cahill at an Oklahoma jail, where Cahill refused to admit robbing the Plano victim, instead claiming it was a “pick-pocket”.
Cahill was returned to Texas to stand trial on the Aggravated Robbery charge. After a motion to dismiss on a procedural challenge of his return to Texas was denied, evidence of the crime was presented including the testimony of the victim. The jury disagreed with Cahill’s early characterization that this was a “pick-pocket,” finding him guilty of Aggravated Robbery.
Cahill will not be eligible for parole until one-half of his 24 year sentence is completed.
Assistant Criminal District Attorneys Abby Nettles Policastro and Lisa Milasky King prosecuted the case. They were aided by District Attorney Investigators Matt Mayes and Ray McCommas. The case was investigated by the Plano Police Department. District Judge Benjamin Smith assessed the sentence.
