SPRINGFIELD, Mo. -- A medical examiner says a man who collapsed while attending a concert last October at the Shrine Mosque died due to effects of methamphetamine use.

Lynn Phillips, 23, died at a hospital after he collapsed at the Life In Color concert at the Shrine Mosque.  According to a police report, others were hospitalized in "varying states of unresponsiveness" as well. 

"The crowd it attracts, the lights and the paint and the rhythm of the music puts them in a mood I'm not sure I want to see again," said Tom Morris, administrator of the Shrine Mosque.

About 1,200 people were at the Mosque on Oct. 4.  Morris said at least 30 people had to go to the emergency room during the event, including Phillips.

"Our hearts go out to the family, but responsibility -- we didn't pass around the drugs, and nobody in our organization would ever do that," Morris said.

During the event, Phillips fell to the ground, experiencing what witnesses described as a seizure, according to the police report.  The report also said tests showed methamphetamine in Phillips' blood.

"We did everything we could possibly do, but yet the young man died," Morris said.

Morris said a paramedic was by Phillips' side within 60 seconds of the collapse.

The police report stated that police and Shrine Mosque staff shut down the concert and took pictures of the venue.  Officers interviewed those who were taken to the hospital, and they admitted drinking alcohol.  Witnesses also reported seeing Phillips "snort" a substance.

Police said they believe Phillips' death was not caused by anyone else. A medical examiner said it was her opinion Phillips died of methamphetamine use and that his death was accidental.

"Hindsight is 20/20.  It draws people that like, the light show, because of the drugs they're using.  I wasn't aware of that," Morris said.

Morris said there were more paramedics and security personnel on hand than usual for the Life in Color concert.

Life In Color, formerly known as Dayglow, is known for people being sprayed with paint during the performances. Incidents involving drugs and alcohol have been reported at other Life in Color concerts, including one at Lehigh University in December 2011. At least 44 people were hospitalized in that incident.

Shrine Mosque staff said Life In Color would not be coming back to perform at the venue again.
