Police believe suspect in 5 Modesto murders also killed 2-year-old

FRESNO, Calif. (KFSN) -- Police in Modesto say a suspect in five murders over the weekend also killed a toddler left in his care last year.

Modesto Police Chief Galen Carroll says a pathologist concluded on Thursday that 2-year-old Christopher Ripley died of head injuries on Oct. 2, 2014.

A warrant was issued for Martin "Marty" Martinez Saturday evening. Earlier on Saturday, two women and three young girls were found slain in a Modesto home. The victims included 38-year-old Amanda Crews and the six-month-old daughter she had with Martinez.

Martinez is also a suspect in those deaths. He was arrested early Sunday morning as he left a San Jose movie theater with his father.
