A woman died and two people were seriously injured in a weekend boating crash in the Matanuska-Susitna Borough. The two injured women are Alice Rademacher and Rosie Robinson, both of Homer and employees at the Kachemak Bay Research Reserve.

According to the Associated Press, one boat driver was jailed on a manslaughter charge after the crash Saturday on Flat Lake.

Alaska State Troopers say a boat carrying seven people was negotiating a curve around an island and sped toward a second boat towing a raft.

The boats turned to avoid a head-on collision but the first boat crashed into the raft, which carried three passengers.

The crash killed 35-year-old Jennifer Horazdovsky of Anchorage. Rademacher and Robinson were on the raft and seriously injured.

The driver of the first boat, 26-year-old Reagan Martz of Anchorage, was charged with manslaughter and three counts of felony assault.

Online court documents do not list his attorney. He remained jailed Monday in Palmer.

KBRR director Coowe Walker told the Homer News that Rademacher remains in serious condition and in a coma at Providence Alaska Medical Center, Anchorage. Robinson is at Mat-Su Regioinal Hospital, Palmer, and awaiting surgery.
