MEMPHIS, Tenn. -- The owner of Emergency Mobil Health Care avoided giving answers on Monday.

"We can't talk about it right now because it is an ongoing investigation."

The private medical transportation company is staying tight lipped about the night Shaun Brown was killed after getting out of the restraints and escaping one of their ambulances on the highway.

Reporter: "So far in your investigation, has it shown any kind of wrongdoing at all?"

Company: "No. Not that I know of."

Family and friends said Brown suffered a psychotic break and was on his way to get help when something went wrong.

"I'd like to know how he got up. How he got up? That's all I want to know. How he got up and how he got out," said Erby Reed.

Those are questions the state health department is asking too.

According to rules set by the Emergency Medical Services Board, a patient must be secured to stretchers except when they need to get treatment.

Everyone on board must also wear seat belts and restrains while the ambulance is in motion.

In order for this ambulance to be fully staffed, state regulations said that a staff member would have had to be sitting in the back of the ambulance with the patient. But it's unclear at this point if that happened.

Loved ones told WREG Brown's death could have been prevented.

"Investigation -- full investigation because something wasn't right . Something wasn't done right. Something wasn't right."

EMHC released the following statement to WREG about the incident:

EMHC adheres to Tennessee EMS rules and regulations for transporting patients per the treating physician’s orders. These procedures are meant to secure, care for and transport the patient with the utmost dignity and respect while ensuring the safety of the patient, medical crew members and public. These procedures include the presence of a medical crew member in the ambulance patient care area and the use of stretcher belts to secure the shoulders, chest, midsection and legs of the patient during transportation.

While federal privacy laws prevent us from discussing patient care, our thoughts and sympathies are with the family. We will continue cooperating fully with the authorities for the duration of their investigation.
