DETROIT (WWJ) – Detroit police are learning more about the murder of a young mother, killed in front of her child, from a suicide note.

Police told Newsradio 950 that the suicide note came from a man who was found dead Wednesday morning in Royal Oak.

Investigators believe he had been dating 29-year-old Shalonna Dowdell who was gunned down Tuesday outside her Detroit home on West Outer Drive as her 5-year-old daughter watched.

Police said the man was being followed by officers when he pulled into a tire store parking lot on Woodward Ave. early Wednesday morning.

No names have been officially released, but family members have ID’d the slain woman as Dowdell.
