FREMONT — The gunshot deaths of a married couple found inside a home Saturday are being investigated as a murder-suicide, police said Tuesday.

The coroner’s office identified them as Holly Lynn Dreyer, 49, and Steven Floyd Howard, 56, who were found dead at the home in the 37800 block Third Street.

An Australian shepherd dog was also found shot to death in the home, police said.

The bodies were found after family members called police and said they could not reach their loved ones and were concerned for their welfare, according to a news release. Officers had to force their way inside the home.

Police spokeswoman Geneva Bosques said police believe the man shot his wife and dog, then went to another part of the home and shot himself.

Bosques said neighbors reported hearing an argument inside the home and then gunshots, which they first thought were firecrackers.

Police said they have interviewed family members, neighbors and other people close to the couple. Based on the interviews and evidence found at the scene, they believe the deaths are a case of murder-suicide.

A motive has not been determined yet and Bosques said there are “multiple facets of the relationship we are looking at that led up to the incident.”
