Expert says defendant's DNA found on gun that killed Metairie father and son

Jurors hear about the high-speed chase leading to the capture of Dexter Allen

GRETNA, LA (WVUE) - The jury in the Dexter Allen murder trial learned Friday how U.S. Marshals captured the defendant.

Allen is accused of committing 19 car burglaries in a Metairie neighborhood before he allegedly walked into a home in April of 2015 and killed father and son, David and Nicholas Pence.

Both were shot multiple times with a shotgun. Prosecutors say Alan and an accomplice, Harquon Degruy, used a stolen white Toyota Highlander to commit the crimes.

Friday's testimony came from U.S. Marshals who said they spotted the stolen SUV in New Orleans East. After trying to stop the SUV, they testified the driver of that vehicle tried to run over a deputy before leading them on a high-speed chase and crashing the SUV on the high rise.

They say Allen ran, jumped off the interstate and was later found hiding in the water of the Industrial Canal.

Prosecutors also showed jurors photos of evidence that was collected from Allen's mother's home in New Orleans. That evidence included a shotgun, found under his mother's home. There was also a spent shotgun shell.

Detectives testified that five shots were fired inside of the Pence home the night David and Nicholas were killed, but only for casings were recovered on the scene. A DNA expert took the stand and testified that Allen's DNA was found on that gun.

Defense attorney Jerome Matthews chose not to make an opening statement and really has not asked many questions of the witnesses in this case. Matthews said that does not mean his client is guilty.

"All these people are coming in. They're saying their cars were burglarized. They're saying all they're saying and of course they were asked, 'Do you know who committed this crime?' and they all say, 'No we don't know.' There is nothing else to ask that witness once they said that. I want the jury to understand that we may not have any questions. We may not have anything to say," Matthews said.

Prosecutors are expected to wrap up their case this evening. The defense is expected to begin calling witnesses Monday morning.
