Sterling Heights man with dementia arrested after stabbing wife, grandson and himself

STERLING HEIGHTS (WWJ) — An investigation is underway after a 74-year-old man with dementia stabbed his wife and grandson before turning the knife on himself.

Sterling Heights police officials say the incident happened shortly before 7:30 p.m. Thursday at a home on Danforth Drive.

The man allegedly attacked his wife with a knife after she woke him up and when their grandson intervened, he also stabbed the 20-year-old.

The man then went into the basement and stabbed himself, according to police. Authorities eventually used a taser to get the man to drop the knife.

The wife sustained superficial wounds to her face and neck, while the grandson was stabbed in the stomach. Both were able to escape to safety outside.

All three were taken to the hospital. None of the injuries appeared to be life-threatening, according to police.

The man was arrested, but there's no word yet on any charges.

"The officers did an amazing job, showing up, providing medical care to the injured as well as confronting an armed and dangerous subject," said Sterling Heights Capt. Mario Bastianelli in a press release. "By utilizing less than lethal weapons to gain control of the suspect, they prevented a deadly force encounter, and were able to get him medical treatment as well."
