Kenner Police Chief Keith Conley provides an update into the death of Kansas City Super Bowl reporter Adan Manzano.

Adan Manzano , the Kansas City sports reporter who was found dead in his Kenner hotel room while in town to cover the Super Bowl, died of asphyxiation while lying face down on a pillow after suffering from the combined toxic effects of alcohol and Xanax, authorities said Tuesday.

Kenner police announced that Danette Colbert, the last person seen with Manzano at his hotel room, will face a second-degree murder charge in his death.

A Kansas City Telemundo reporter, Adan Manzano, died Wednesday while covering Super Bowl LIX in New Orleans, Telemundo Kansas City said on social media.

The new charge comes more than a month after police first booked Colbert with robbery and fraud for allegedly using Manzano's debit card after his death.

The murder warrant was based on a combination of all the evidence investigators have obtained thus far, said Kenner Police Chief Keith Conley, who acknowledged the case against Colbert is circumstantial.

"Circumstantial cases are tough, but there is certainly a place for them," he said.

On Tuesday, Conley also revealed police had arrested a second suspect in the case. Rickey White is accused of being involved in the fraudulent use of Mazano's debit card.

Danette Colbert, left, and Rickey White, were arrested on robbery and fraud charges related to the theft and used of a debit card belonging to deceased Super Bowl reporter Adan Manzano.

"There was some correspondence and information where they (White and Colbert) were going back and forth, so we think they were working hand in hand, in concert with this," Conley said.

French Quarter meeting

Manzano, who worked for a Kansas City affiliate of Telemundo, was discovered dead in his room at the Comfort Suites in Kenner on the afternoon of Feb. 5 after co-workers reported that he'd missed a meeting, authorities said.

Surveillance video showed Colbert with Mazano in the New Orleans French Quarter, where authorities suspect they met, and at Mazano's hotel just before dawn on Feb. 5, police said.

She was seen leaving his room about 6 a.m. His body was discovered later that afternoon.

Colbert was booked two days later with simple robbery, computer fraud, bank fraud, illegal transmission of monetary funds, purse snatching and access device fraud after police say she used Manzano's debit card at a store.

His cell phone was also recovered at her Slidell apartment, police said.

Cause of death

A preliminary autopsy determined that Manzano had the drug Xanax, a depressant, in his system. But the Jefferson Parish Coroner's Office held off on identifying a cause of death until they could complete more thorough toxicology testing, authorities said.

On Tuesday, Jefferson Parish Coroner Dr. Gerry Cvitanovich said that in addition to Xanax, brand name for the drug alprazolam, Manzano had alcohol in his system. Manzano's blood alcohol was 0.232%, almost three times the 0.08% legal limit.

Manzano had 25 nanograms per milliliter of Xanax in his system. While not an overdose level, Cvitanovich said that both the drug and the alcohol are central nervous system depressants which, combined with Manzano's face-down position in the pillow, led to his death.

Manzano's manner of death is undetermined. A person's manner of death can be classified as a homicide, suicide, accidental, natural or undetermined, Cvitanovich explained.

"Given the uncertain circumstances of this case and the additional collection of circumstances, we felt the most appropriate manner of death was undetermined," he said.

Other investigations

While Manzano did not have a prescription for Xanax, nor was any of the drug found in his hotel room, investigators did find the drug during a search of Colbert's Slidell residence, police said previously.

Colbert previously been accused of targeting men she meets out in the French Quarter and drugging them to steal money, credit cards and other property, authorities said.

State Police Troop Nola and the Louisiana Attorney General's Office have joined the investigation into Colbert's alleged activities in New Orleans at the request of local authorities.

In New Orleans, authorities are investigating her suspected involvement in the Dec. 15 death John Jenkins . The 55-year-old from Maryland was found dead at his French Quarter hotel of cocaine and ethanol toxicity, authorities said.

Colbert has not been booked in that death.

"I can tell you we don't want Ms. Colbert to see the light of day again," Conley said.
