A lake on the border of Utah and Arizona is the site of a search today after a motorboat and houseboat crashed into one another on Thursday.

Authorities say one woman was killed in the crash and two other women are missing but presumed dead. The victim, Marilyn Jackman, was 57 years old and was the wife of the driver of the motorboat, 59-year old Adrian Jackman. His daughter, Jessica Jackman, and another woman, Valerie Rae Bradshaw, are the subjects of an extensive search of Lake Powell. He was taken to the hospital along with his 11-year old daughter and another passenger via helicopter but all three were treated for non-life threatening injuries and released.

Kane County Sheriff’ Sgt. Alan Alldredge said they received a call about the crash a little after 8 a.m. on Thursday; Jackman allegedly became distracted by the children on his boat and lost control, colliding with the houseboat. None of the passengers on the houseboat were injured.

“This time of year, the lake can get busy and these kinds of accidents, even though they’re not rare, they do have a great potential for happening out there,” Alldredge said.

Officials say the motorboat overturned after the collision, which happened in a channel about 200 yards wide.
