Two Grapevine teenagers who were found dead Jan. 5 in a Grapevine home died from a lethal cocktail of heroin, codeine, alprazolam and diphenhydramine, the Tarrant County Medical Examiner ruled.

The deaths of Chase Nunez, 18, and Kyle McNutt, 17, both seniors at Southlake Carroll High School, were ruled accidental.

Alprazolam, used to treat anxiety disorders is also known as Xanax. Diphenhydramine, an antihistamine, is found in Benadryl.

Grapevine police say Cullen Marino, 22, provided drugs to the teenagers and then failed to call 911 after he found them unresponsive in the middle of the night.

Marino, a graduate of Colleyville Heritage High School, faces two charges of criminally negligent homicide. Police have said additional charges could be added.

The two teenagers were discovered by Cullen's father, Bob Marino, in an upstairs bedroom of his home and he called 911.

"I might have two dead kids upstairs in my house," he said in a 911 call released January 7 by Grapevine police.

He told a dispatcher that he attempted cardiopulmonary resuscitation on one of the boys, but was unsuccessful.

When the dispatcher asked if the boys had taken drugs, Bob Marino asked Cullen Marino.

"He says if they did it, it had to be before they came here," he told the dispatcher.

But police contend that Nunez and McNutt were provided drugs by Cullen Marino.

When they arrested him, police said they found a spoon with heroin residue in the front pocket of Marino's pants.

Bob Marino told investigators he was unaware of what had happened upstairs. He told the dispatcher that he heard the boys after 10:30 p.m. Jan. 4 but the teens were dead when paramedics arrived on the morning of Jan. 5.

A search warrant affidavit said Cullen Marino told police that several friends, including Nunez and McNutt, were at his Grapevine home when he returned from Dallas after buying drugs. The friends drank alcohol and ingested marijuana, possibly heroin and another drug throughout the night, police said.

Police seized glass pipes, bongs, marijuana, scales, Xanax pills, white powder and orange pills from inside the house.

Cullen Marino faces two charges of criminally negligent homicide because he found the two teens unresponsive and didn't call 911, Grapevine police said. Rather than call authorities, Marino and some of the other friends carried the two teens to a separate bedroom and left them there, according to the affidavit, then he went back to sleep.

A 2008 graduate of Colleyville Heritage High School, Cullen Marino has a criminal history in Tarrant County.

Just months after he graduated from high school in 2008, Marino had three cases of marijuana possession filed against him in Bedford and Grapevine, and one case of driving while intoxicated in Grapevine, according to Tarrant County criminal court records.

At that time, he was on two years' probation on the DWI charge out of Grapevine, records showed.
