Police dispatchers took a call for medical assistance at an apartment in the 500 block of E. 13th Street in the early morning hours.
When officers arrived, they found a 29-year-old man dead inside the unit.
Authorities said the man had a non-life threatening injury and if his injury had been treated properly, he would have survived.
Later in the day, police got a call about a bloody scene found at Memorial Park on Foothill Boulevard. Police said they were investigating whether the man's death is somehow connected to the scene.
