As he stood near the playground in front of the large crowd on Friday, Gov. Mark Dayton grappled with finding the right words to comfort the students of Peter Hobart Elementary School who were mourning the deaths of two of their own.
"I wish I could say something that would make you feel better," Dayton told the audience of children, teachers and parents. "I wish I could say something that could explain to you why this terrible thing happened. I can't."
To get more answers as to what caused a landslide at Lilydale Regional Park earlier this week that killed and injured students on a fossil-hunting field trip, the city of St. Paul said Friday that it hired a civil engineering firm with geotechnical expertise to examine the site.
The city chose Northern Technologies Inc., which has offices in Minnesota and North Dakota. The company expects to provide information on the landslide to the city within the next several weeks.
"With particular expertise in the evaluation of collapses and natural disasters, we expect their work to provide us with a better comprehension of what caused this tragic accident," said Mike Hahm, director of St. Paul Parks and Recreation, in a statement.
Mohamed Fofana, 10, and Haysem Sani, 9, were killed in the landslide at the St. Paul park on the bluffs of the Mississippi River while they were on a trip with their fourth-grade class on Wednesday. Their funerals were Friday.
Two other students, identified by the school as Lucas Lee and Devon Meldahl, were injured. Devon was admitted to the Level I Pediatric Trauma Center at Regions Hospital and Gillette Children's Specialty Healthcare. He was listed Friday in fair condition. Lucas was released from the hospital earlier this week.
Following the landslide, the city closed access to the fossil grounds, a popular school field trip destination, until further notice.
Before class started on Friday morning, students huddled around a memorial of flowers, teddy bears and balloons at the front of the school.
