Dexter Morgan amazes Mike Anderson by solving the crime within seconds

Beach House Murder-Suicide Case is a police investigation in Season Six of Showtime's series DEXTER.

It involves the deaths of a married couple.


A husband and wife, married for an unknown number of years, lived in a rented beach house. At some point, the husband started stepping out on his wife with a young, brunette Asian woman. The wife discovered this when she saw an incriminating photo of her husband and this unnamed woman on his phone. She took her revenge on her husband by first throwing the phone at him. Then she grabbed a gun and shot him. Feeling remorse, she then killed herself.

He also found a cellphone under furniture that appeared to have been thrown at him by his wife. This was confirmed when the murder weapon (a gun) was found underneath her body.
