A man shot a woman and her infant son to death inside of a home in Deerfield Beach Thursday morning, then turned the gun on himself, but survived, deputies say. He is now in critical condition in the hospital.

Andre Lanns, 27, was arrested Thursday on two counts of first-degree murder in the killing of Marrina Guadagnino and her son, Andre Lanns III, the Broward Sheriff’s Office said Friday. Though the name would indicate that Lanns is the father, the relationship between Lanns and the woman and son could not immediately be confirmed by deputies. Just before 6 a.m., Broward Sheriff’s Office Deerfield Beach deputies responded to reports of a shooting in the 4000 block of Eastridge Drive, according to a media release. There, they found Lanns in the street with an “apparent self-inflicted gunshot wound.”

When deputies went into a nearby home, they found Guadagnino and the infant boy with gunshot wounds. Both were pronounced dead. The release did not provide the age of the boy.
