OLD TOWN (AP) — State police said the Old Town woman fatally stabbed by her boyfriend this week was pregnant.

Police said 35-year-old April Haskell was killed by her boyfriend on Wednesday night before a state trooper responding to the couple’s apartment shot and killed the boyfriend, identified as 28-year-old Christopher Ouellette.

An autopsy Thursday determined that Ouellette died of a single gunshot wound to the head. An autopsy on Haskell is scheduled for Friday.

The couple had children ages 2 and 4 together. They were in the apartment, but unharmed.

Police say the couple had been together about six years and Haskell was a housekeeper at a Bangor hotel.

The trooper who shot Ouellette, 15-year veteran Barry Meserve, has been placed on paid administrative leave pending the investigation.
